Griffin Rising is Darby Karchut's debut novel. It's about a guardian angel named Griffin, and if you're like me, you'll fall in love with the sixteen year old, as if he were your own son. The bad news is the book won't be out until June 2011, but go ahead and add it to your list because you'll definitely want to read it. I promise. The good news is there will be another book about Griffin and another.
Beautiful Darkness, by Kami Garcia & Margaret Stohl is "beautiful." It continues the story of Lena Duchannes and Ethan Ware and the small town of Gatlin, "where impossible, magical, life-altering events happen." (From the book jacket.) A real page turner.
Add Becca Fitzpatrick's Crescendo to the list, and I've read some great stories this fall. This book is about Nora Grey, the heroine we met in Hush, Hush, and her life with her guardian angel, Patch, who is quite different to the guardian angel in Griffin Rising.
