Beyond the sunset - Kathleen Duey

Heart is still on the run from the wicked Lord Dunraven with her beloved unicorns, Moonsilver and Avamir. She's sure that the small book she found in his castle holds the secret to finding a safe haven for them all - especially when a village blacksmith tells her of some ancient iron gates, decorated with the same unicorn designs that appear in the book. But what lies on the other side of these mystical gates, beyond the sunset? Will the book also unlock the key to Heart's memories and help her discover who she really is?
As Heart struggles to learn to read and protect the unicorns at the same time, she knows Lord Dunraven's men are drawing closer all the while…
This is the third book in the exciting series, The Unicorn's Secret.
