Sunchaser's Quest (Unicorns of Balinor, #2)

Princess Arianna has returned to Balinor--a peaceful, magical world watched over by a herd of beautiful unicorns. But a dark presence has invaded the land. And Arianna has no memory of her past or how to tend to her wounded unicorn, Sunchaser.

The unicorn's horn was broken in battle, and he is very weak. The journey to get Sunchaser's horn restored will be long and very dangerous.

But it is Sunchaser's only hope. And--as Arianna and Sunchaser soon learn--the only hope for all of Balinor.
