It was an easy choice. There's really only one book that stole my heart that way. I wonder, is it still stealing if you're glad it was taken, and want the thief to keep it forever?
Life of Pi, by Yann Martel
I am absolutely smitten with this novel. It has animals and God and adventure on the high seas, so what, exactly, is in here not to love? Yann Martel had me at this book was born as I was hungry. And from that first line to the last, he never let me go.
