I was working on a punny post title like "Mr. Chick-lit" -- combining chick lit plus mystery. But it didn't work.
I like Carol Goodman because her books are interesting enough to hold my attention, well-written enough to keep me from being annoyed, but light enough to read when I don't have a lot of brain left for concentration. The Drowning Tree fits that beautifully, combining (fake) art history with human drama plus a whodunnit. Nice, simple, satisfying. And readable even when my eyes close after about two pages a night.
