Susin Neilsen's We Are All Made of Molecules
Neilsen is a former writer for Degrassi, and it seems like she still has her figner on the pulse of young people, because this novel rang really true to me. It's the usual popular girl-nerd boy blended family sort of thing, but the characters all feel real (minus the girl's constant malapropisms) and it made me cry more than once. Maybe the end is a bit too pat, but I didn't care, I thought this was a really nice book. Warnings for some rapiness. B+/A-.
