Notes
Something strange is happening to Claire's sister Sophie, and Claire is desparate to find a cure. But Queen Estelle has returned to Arden determined to seize power. She intends to destroy the last unicorn, and only the mixed magic of the four guilds will stop her. If Claire can unite the four pieces of the broken crown of Arden, perhaps it will bring the guilds together before all is lost. But if her plan fails, can Claire protect the last unicorn from the queen and bring her sister safely home?
