The Silver Tower. Rise of the King, #2

Merlin has been missing for over a thousand years. Now the search for him could cost Tom everything. Tom has chosen the Otherworld. With King Arthur newly awakened and his cousin Beansprout by his side, life in this world of ancient magic, shape-shifters, and fey royalty is everything he hoped it would be. Then Vivian intervenes. Nimue, powerful witch and priestess of Avalon, has vanished on a secret quest.
Vivian needs Arthur to find her. Arthur needs no persuasion. He's already convinced Nimue is searching for the one person he lost and never stopped mourning: Merlin. The trail leads to Holloways Meet, but what they discover there makes no sense. Nimue isn't lost. She's hiding something, and she's far more dangerous than anyone anticipated. To find Merlin, they must cross the Blind Moor, navigate the treacherous politics of Dragon's Hollow, and face dragons, a dragon sorcerer, and the enigmatic sylphs, spirits of the air who answer to no one.
And Tom must decide how far he'll follow Arthur into danger before the new life he loves is lost for good. Myth runs deep, magic runs wild, and old loyalties cut both ways in this gripping second instalment of the Rise of the King series. For fans of Rick Riordan, Kevin Crossley-Holland, and T. A. Barron.
