I'm a library fanatic, so I usually end up browsing at the local library until I find one or two books that look interesting. My local library actually has an "Undiscovered Gems" section that has lead me to some interesting reads from authors I'm not familiar with. I also keep a running list of interesting titles on my library account, putting holds on them as I finish books.

I'm like you, I usually bounce around between fiction and non-fiction to keep my reading balanced. For me, half the fun of reading is simply exploring and discovering new books/authors/series!
