At present, the best general single-volume monograph history on the Qing in English is William T. Rowe's China's Last Empire: The Great Qing (2008). It is not without its problems: as a review by Pamela Crossley notes, it is quite Sinocentric in focus, and its narrative of the nineteenth century is quite traditional and doesn't fully draw on newer historiography to the same extent as the earlier part of the book. There is, however, nothing as yet to supplant it as an overall view. The trouble is that the more detailed alternative, which are volumes 9, 10 and 11 of the Cambridge History of China, suffer from a similar problem: the two halves of Volume 9 (covering ~1600-1800) are quite recent and historiographically up-to-date (they were published in 2002 and 2016), but 10 and 11 (covering ~1800 to 1912) are some two decades older than that (1978 and 1980 respectively), and so are now out of date. For that later period Pamela Crossley's A Wobbling Pivot: China Since 1800, An Interpretive History (2010) is a good modern alternative.

From the 1990s onwards, the so-called 'New Qing History' (better understood as a paradigm shift rather than a historiographical school as such) has brought about significant changes in how we view the Qing. A few monograph highlights would be:

• Evelyn Rawski, The Last Emperors: A Social History of Qing Imperial Institutions (1998) – Looks at the institutions of the Qing imperial court and their reflection of a plurality of influences beyond the traditions of the Ming and their predecessor Chinese states.

• Pamela Crossley, A Translucent Mirror: History and Identity in Qing Imperial Ideology (1999) – Discusses Qing ideology, particularly under the Qianlong Emperor, particularly through the lens of its distortion of early Manchu history.

• Mark Elliott, The Manchu Way: The Eight Banners and Ethnic Identity in Late Imperial China (2001) – Covers the development of ideas of ethnicity and identity within the Eight Banners under the Qing, and the Qing state's attempts at inventing a Manchu tradition in the 18th century. Challenges Crossley on some points and concurs on others.

• Edward Rhoads, Manchus and Han: Ethnic Relations and Political Power in Late Qing and Early Republican China, 1862-1928 (2000) – Continues the focus on ethnic politics, looking at how ethnicity played into the political dynamics of the later Qing state leading up to its collapse.

• Evelyn Rawski, Early Modern China and Northeast Asia: Cross-Border Perspectives (2015) – Argues for a decentering of Asian history from China, positing a trans-state environment in the broad region of Northeast Asia, wherein the organised sedentary polities of China, Korea and Japan interacted with the steppe polities of Mongolia and the tribal polities of Manchuria and eastern Siberia, to mutual effect.

• Peter C. Perdue, China Marches West: The Qing Conquest of Central Eurasia (2005) – A magisterial work covering the process by which the Qing conquered its territories in Mongolia, Tibet, and Eastern Turkestan, and its implications for the structure of the Qing state and our understanding of it.

• James Millward, Beyond the Pass: Economy, Ethnicity, and Empire in Qing Central Asia, 1759-1864 (1998) – Covers developments in Qing imperial policy in post-conquest Xinjiang.

• Laura Hostetler, Qing Colonial Enterprise: Cartography and Ethnography in Late Imperial China (2001) – Looks at Qing policy in Guizhou province as an example of Early Modern colonialism, seeing developments in mapmaking and ethnic categorisation as reflections of a growing discourse of superiority.

• Emma Teng, Taiwan's Imagined Geography: Chinese Colonial Travel Writing and Pictures, 1683–1895 (2004) – Similar to Hostetler above, Teng approaches Taiwan as a Chinese colony in the Qing period through the lens of how members of the coloniser population (Han Chinese) conceptualised the region over time.

• Johan Elverskog, Our Great Qing: The Mongols, Buddhism, and the State in Late Imperial China (2006) – Discusses how the Mongols came to identify as being part of the Qing state, which he argues successfully presented itself as a Buddhist monarchy that transcended the immediate bounds of the Mongolian steppe.

• Max Oidtmann, Forging the Golden Urn: The Qing Empire and the Politics of Reincarnation in Tibet (2018) – Looks at the controversies that caused and were caused by the introduction of the Golden Urn in 1792, whereby the Qing required that the reincarnation of Tibetan lamas be decided at random from a shortlist rather than fully entrusted to the arbitrary decision of the existing Tibetan clergy. In particular Oidtmann argues that the Tibetans themselves cooperated with the Qing to a greater extent than modern exiles have asserted.

• Seonmin Kim, Ginseng and Borderland: Territorial Boundaries and Political Relations between Qing China and Chosŏn Korea, 1636–1912 (2017) – Approaches Qing-Chosŏn relations in not just political terms, but also environmental ones, looking at how the two states interacted with a focus on their approaches to the border region's natural resources.

There's also a few edited volumes that cover some aspects of Qing history from various angles; of particular note include:

• Joseph Esherick and C.X. George Wei (eds.), China: How the Empire Fell (2014) – An edited volume of translated Chinese articles on key aspects of the last decade and a half of the Qing period, with a largely 'New Qing'-adjacent editorial focus.

• James Millward, Ruth Dunnell, Mark Elliott, Philippe Forêt (eds.), New Qing Imperial History: The Making of the Inner Asian Empire at Qing Chengde (2004) – A collection of articles focussed on the Qing summer palace complex at Chengde (also known as Rehe or Jehol), and its reflection on the wide Qing empire.

• Lynn A. Struve (ed.), The Qing Formation in World-Historical Time (2004) – A collection of articles focussing on the earlier part of the Qing, with a focus on global connections and conceptions of global Early Modernity.

• Pamela Kyle Crossley, Helen F. Siu, Donald S. Sutton (eds.), Empire at the Margins: Culture, Ethnicity, and Frontier in Early Modern China (2006) – A collection of articles discussing matters of identity and ethnicity in the Qing, partly looking at Inner Asia, but in large part focussing on non-Han in 'China proper', such as Muslims in northwest China, and indigenous peoples in southern China.

The above has been by all means non-exhaustive, and focussed mainly on the more vibrant discourse around the earlier part of the Qing, so if there are any aspects you'd like me to offer more on do please ask and I'll try to provide.
