I'm sad that the Spenser series has come to an end, but I'm really enjoying going back and re-reading all of them, and there are a lot! The fourth book in the series,
Promised Land, is really good and only $.99 at Copia. It's also the only book in the series to win an Edgar Award for best book. Hope you enjoy it too! Link is below:
