I love World War 2, how much it changed the world, the people that led during that time, the weapons that were created, and the battles. I know quite a bit about the war for my age, and am looking for a more "advanced" read that gets in to detail about stuff. Any topics are welcome I would like to further my knowledge on the subject.
EDIT: I don't love World War Two, more fascinated by it, Ik it took millions of lives, and that is horrible. I really don't know how to explain it.
I love World War 2
You shouldn't. Really, you shouldn't.
On a more serious note, let me recommend a few more or less general books to give you an "advanced", as you say, overview. I assume you're not an adult, but neither are you a child.
Norman Davies, Europe at War. This is my go-to recommendation whenever somebody asks for texts on what WW2 was like. What I respect the most about the book is it attempt to show a proper proportion between the Eastern and Western fronts in Europe.
Richard Overy, The Dictators, should be of interest to you since you 'love . . . the people that led during that time.' Though this particular book is about two people whom you should specifically not love, Hitler & Stalin. It's a long and detailed piece which will give you an interesting and comprehensive view of this devilish duo.
Colin Smith, Singapore Burning. An extremely detailed account of the Japanese conquest of Malaya. What I like most about this book is its vivid depiction of the demise of the Prince of Wales & HMS Repulse.
And if you'd like a more jounalistic perspective of key Western front battles, you really need to start with the major works of Cornelius Ryan, i.e. The Longest Day & A Bridge Too Far.
Tricky question! There are so many books on a war that had so many different features. Continental warfare, submarine warfare, air fights, partisan civil war: WWII had it. I've become most fascinated by the Eastern Front, but I bet you can find something on everything.
Red Road from Stalingrad began my interest: it's a really great Eastern Front bio told from the POV of a Soviet sniper and mortar team. The characters truly come alive.
When Titans Clashed does a great job at mentioning nearly all East Front battles, and dispels a shitton of beliefs I once had about the war.
Anything by Forczyk will be a fun read. He writes both for himself and Osprey Campaigns, a really well-illustrated military book series.
The Dnepr: 1943 was my favorite so far because it discussed a campaign I never even heard of in the Ukraine, but his newest book, Red Steamroller, is a great analysis of armored tactics.
Knights Move: Osprey book on the Yugoslav partisan conflict.
Touched with Fire is the best analysis of the early Pacific War I've ever seen, exploring the men, the tactics, and the weapons at Guadalcanal in great detail.
