When Isolde goes missing, Michael and Declan spend months trying to find her. When they eventually track her down, they are dismayed to discover the person who was their mate is now part of a criminal pack, with no memory of her previous life. They must persuade her to leave her life and her pack, and convince her she wants to be someone else - the Izzy they know. Until they know she is no threat to her own cubs, Isolde cannot return home. With the criminal pack on their tails, and its leader determined to have Isolde as his mate, they are in another race against time to prevent her inventing new memories to replace the old ones. Helping her to recover her memories of being a wyrdwolf is more tricky than they expect. To do that, they have to track down the magician who brainwashed her - and unlock the mystery of a story that disguises secrets that go back a century. In the end, the only chance they have to recover the lost wyrdwolf is to find out who arranged Isolde's kidnapping and to take sides in a bitter family feud.
