I've finally read Repairman Jack #2, Legacies (Repairman Jack Novels (Paperback)). It's a damn good book.
This one takes place shortly after The Tomb, and well before Jack begins to be constantly involved with the Otherness. The plot of this one actually kept me guessing until very close to the end. A woman has been willed a house, and there's some sort of mystery inside. I didn't figure out what the mystery was until just before the characters figured it out, which is pretty rare for me. This might be because, based on the other Repairman Jack books, I expected a supernatural secret, but it was in fact super science.
Anyway, the Repairman Jack books are great. This is no exception. I give Legacies five yo-yos. If you wondered about the Samurai Jack reference in the title, it's because Jack is referred to as a ronin a couple of times in this book.
