I feel like I'm back in school, reporting on my progress on reading this year! Inagoodway...
Going with the concept that my top three choices will be books that have remained in my memory and/or that I reread (I'm a HUGE rereader of books I loved...):
SHIELD OF WINTER and SHARDS OF HOPE by Nalini Singh. (These
two count as one in my unique Saturday Algebra System of Accounting.) I reread both of these, but especially SHIELD. Something about the Psy Arrow Vasic just gets to me. I love the way Nalini tells his tale, and shows how his Empath Ivy (and her dog of course) bring him out of his self-imposed mental prison. Her Psy/Changeling series is one of my all time favorites and I continue to read each new book avidly. No series dropoff here! Oh, and since Aden (SHARDS) and Vasic are such close friends and allies, the two books absolutely go together in my mind.
And for the bonus question: WOOL, DUST and SAND (THE SILO SAGA) by Hugh Howey. I was under the weather after a minor medical thing recently and I read straight through these. I was a latecomer to the whole SILO thing, although I'd previously read some intriguing short stories from Mr, Howey, set in the same world. I was utterly fascinated by the world building, the politics, and the way life had developed inside the silos, with all the specialization...I probably ought not to have read all three back to back because I was flagging a bit by the end and I got pretty tired of certain people who created the Silos in the first place (no spoilers from me). Certain parts toward the end also reminded me of "Wayward Pines". Not in a bad way and I've no idea which came first and there are only 8 basic stories in the world anyway, right? But I was still amazed and awed at this set of books when I finished the final page.
