I have just found the coolest site — Book Seer! You type in the title and author of a book you have just read and it generates recommendations for you (using Amazon and LibraryThing). Unfortunately it is not all-knowing, so sometimes it has nothing to recommend. But I hit the jackpot with Redeeming Love by Francine Rivers.
Check it out by clicking here.

Hi…I checked it out, and it’s neat…Thanks for the suggestion…
