Dream Walk — Brenna Lyons

From the age of five, all of Sanctum has known Jaden would marry the Mage Lord's eldest female heir, but Rachel has no interest in being Jaden's mate. In fact, she denies that she is Jaden's mate and insists that the Mage Prophet who foretold it was wrong.

As a Dream-Walker, Jaden can enter the dreams of anyone who asks for his help. The only dreams he can enter uninvited are those of his mate. But when he's drawn into his mate's dreams, he finds much more than he bargained for. His mate is in danger...and she isn't Rachel. He discovers that Lara is the Mage Lord's eldest female heir, an heir no one within Sanctum knew existed.

Now it's a race against time. A rogue wants Sanctum, and Lara is his way in, if he gets to her before Jaden can.
