Looking up the review on amazon is more the second step anyway. First you need to know about a new book you like. Looking up the new releases of the publisher didn't help me either.
Than I read about gooreads. In this social network you add your own book list and rate your books. After this you find easily new books you like.
This soundedn good, but
- the reviews are even worse than on amazon
- a book may list several times (Paperback, Hardcover, reprint?) - The Eagle Has Landed (Paperback)
by Jack Higgins has 9 entries
In this state it is of no help and I have to search/wait for the next solution.
