Blue Bloods writer Melissa de la Cruz and her husband Michael Johnston are joining forces for a young-adult trilogy called The Other Land Chronicles.

The couple has signed with Penguin Group’s G.P. Putnam’s Sons Books for Young Readers imprint. 3 Arts Entertainment literary agent Richard Abate negotiated the deal with Jennifer Besser. Frozen, the first book in the series, will be released in spring 2013.

Here’s more from the press release: “Set in 111 C.D., one hundred and eleven years after a Catastrophic Disaster has wiped out 99% of humanity and left the earth covered in ice, this new series introduces readers to a ragtag group of friends and the dawning of a new time. The world of reason, of mathematics and science, is ending, and a new civilization is being born from the ice: a world of magic and mayhem, sorcerers and spellcraft.” (Photo Credit: Denise Bovee)
