The last secret

Isa's life is suddenly turned upside down. Everything she loves seems to be lost in an instant: her grandmother's cozy farm, the horses Isa loves so much, and Omi herself, whom she could always count on. Isa longs to find solace in the one horse she feels a special bond with: Randalin. But even that horse seems to be taken from her. Before Isa fully realizes what's happening, she's traveling with her grandmother through wild, untouched Iceland, searching for a secret from Omi's past. But is her grandmother still capable of such a journey? Will they find what they're looking for? And what will Isa's life be like when they return home?
