Ha! So, most of the books you folks are mentioning have been either sitting in my queue, or popping up in my recommendations. This helps weed through things!
I continue to essentially stalk Neil Gaiman for news of American Gods 2 (write faster, Neil) as well as The Winds of Winter by GRRM (but that’s a 13 year struggle, so I’m used to waiting. But still, write faster George).
RG, I got just the thing for you. The first time I saw this, I was cackling for a good five minutes straight. ^-^
Also, there might be a sequel to AG??? When??? (Also, if you like Gaiman, have you read anything by China Mieville?)
On YA — it’s not a genre I normally gravitate to, but one series that I cannot recommend enough is Laini Taylor’s Daughter of Smoke and Bone. It’s the first of a trilogy (and all three are excellent). It’s one of those things that will keep you reading in the wee hours of the morning. It’s phenomenally written, the world is fascinating and just the right kind of haunted/haunting, and the characters are very odd but they sort of stay with you even after the books are over. Like many YAs, there’s a love story at the center, but it’s done in a very unusual way, and it plugs right into the cosmology of the world, so it doesn’t feel artificial. Seriously amazing.
