Among Thieves by Douglas Hulick
The reader who drew this book also picked The Lies of Locke Lamora, so she naturally compared them because the main character in both books is a thief who lives in an unforgiving society. The difference between the two books is the size of the criminal organization of which the hero is part. In this book it's a big one; in Locke it's really small.
There's less depth in this book. The story is more straight forward, making it easier to read and follow.
Neither book made her want to read the sequels. This is the reader who loves the Greywalker and Hallows series, so she's fond of urban fantasy instead of medieval or Renaissance ones. Like I said, next time we parcel out the books differently.
