Poppy Curses and Emerald Skies

Oz is not safe anymore. After a glowing green object lands in her front yard, Dori wakes up in a strange land where warriors are forgetting their names, citizens are fleeing to the forest for sanctuary, and any mention of the Enchantress elicits fear. Dori wants nothing more than to get back home. However, she finds herself drawn to the three guardians of Oz: East, North, and West. Each with their own curse, Dori discovers that she has a crucial role in helping break these curses and in defeating the evil Enchantress.
Can Dori help restore the balance to Oz before the Enchantress finds her? Or is Oz destined to be cursed for eternity?
