For any Mercy fan, this is a must read. While Mercy only appears in one story, all the stories involve characters a true fan would know. You learn Samuel and Ariana story, you learn about how Moria and Tom meet, you get to know how Thomas becomes a vampire, you get to know more about David and his family, and you also get a few outtakes from Mercy books. The collection contains all the previous published shorts from the Mercy Universe as well as few new ones. The only draw back is that if you haven't read both the Mercy and A&O series, you may not know all the characters, but getting to know them will only make you want to read the series more. It was wonderful to spend time with characters that only make brief appearances through the series, but made an impact on the stories in Mercy's world.
