To rescue her Jess must capture one of them - a shapeshifter, a kelpie - but he's nothing like she imagined. Finn sees her in ways that no one ever has. Not even Magnus, who's known her all her life. Caught between two worlds, Jess must choose between what she's always known and what lies... Beneath.

Summer has been stolen. Eternal winter threatens. St Andrews is not known for its glorious weather. But when the sea starts to freeze and ice creeps up the beach, Josh's summer holiday becomes a lot more dangerous. Josh and his new friend Callie are thrown headlong into a storm of witches, ice creatures, magic and the Winter King. A permanent winter threatens, unless they can stop the Winterbringers once and for all ...

15-year-old Callie Hall has just found out she's a witch, and things keep going wrong. Sometimes her mind seems to make things happen, things she can't control. She can set fire to things without a match, and when she's angry people can get hurt. Her friend Josh understands she's a bit weird, but its only on a dark and dangerous visit to the tunnels under the ruins of St Andrews' castle that he realises just how strange she really is. Something comes back with Callie -- in Callie -- something she can't escape. Can Callie control her power long enough to send back the darkness, before it takes over her life? And will Josh ever understand her secret? A brilliant, engrossing teen fantasy from the author of Winterbringers and The Keeper's Daughter.
