I'm addicted to the genre so as a rule my favorite HR is the one I've just finished (unless it bombed which happens from time to time.)
However on refelcton my favorite is 'Love in the Afternoon' by Lisa Kleypas.
I started reading it because the heroine, Beatrix, loves animals but I became enchanted by the way that Ms Kleypas uses Beatrix's patience to help heal Christopher who is suffering from the Crimean equivalent of shell-shock.
What about you? Any good recommends from 2010?
