Yes—the hardcover is finally out! I made it live just before I left for Dragon Con, and by now it should have trickled into all the store catalogues. I think it came out great!
If you would like to ask your local library to order a copy (Please do! Ask nicely, but ask!), you can tell them it’s available from Ingram, and the ISBN is 978-1-61138-834-3. Same info applies to your local bookstore.
It’s also available from Barnes & Noble online: http://bit.ly/ReefsBNhardcover
