I won?

I just checked my mailbox and... surprise! I had received a book from Grove Atlantic.  I don't remember being notified that I won this book, but I assume that I must have won a drawing from The Lineup  for a giveaway they held in March? I honestly don't know and I don't remember them asking for my address so...I don't know? But anyway, thank you to the author, publisher, and whomever else was responsible for me receiving this book:

I will start reading it soon.
