I'm in a medieval history class currently, and it's frustrating to have class after class filled with men rulers, scholars, and figures with women as main figures interjecting once a week. I've looked at the recommended women's history books in the book list on this sub, but unless wondering of anyone else had other recommendations, specific to prehistoric to medieval women's history.
Some great secondary sources:
Caroline Walker Bynum, Holy Feast and Holy Fast - "Medieval women ate, cooked, partied at celebrations, and starved durings famines. Medieval holy women, it was said, starved themselves to imitate the suffering of Christ on the cross, and feasted on nothing but the Eucharist--the body of Christ himself!--to bring their souls to union with God. Oh, and some of them skipped the food part and wrote some amazing and amazingly trippy things about the experience of union. Bynum almost singlehandedly taught medieval religious historians to pay attention to women, and this book is the cornerstone of how she did it." (quoting myself)
Delia Cortese and Simonetta Calderini, Women and the Fatimids in the World of Islam - There aren't that many books on women in the medieval Muslim world, period. This is a good one, with fantastic stories of individual women and good background for placing them.
Eric Dursteler, Renegade Women: Gender, Identity, and Boundaries in the Early Modern Mediterranean - Ignore the too-scholarly title. The book is essentially three stories about "renegade" women--renegade being the medieval term for people who converted from one religion to another. (Typically used by Christians to mean people who converted to Islam. Dursteler discusses women who did both versions.
Henrietta Leyser, Medieval Women: A Social History of Women in England, 450-1500 - "*Medieval Women serves as a good introduction to the roles played and lives lived by women in medieval England from the mid-5th century through to the start of the 16th. Leyser creates an original synthesis from the available archaeological and written records to discuss their roles in all aspects of society, from wage labour to motherhood to the crafts to the economy and to religion" (quoting /u/Hergrim) (Why always England, says the historian of medieval Germany...)
And from the women's history list, Bennett's Ale, Beer, and Brewsters is great.
If you're interested in primary sources at all, let me know! My username is from a poem by a TOTALLY AWESOME medieval woman mystic, Mechthild of Magdeburg:
Here's the full poem, as translated by Frank Tobin. And the line itself:
Du luhtest in die sele min
Als die sune gegen dem golde
You shine into my soul
Like the sun against gold
