Merry is bubbly, outgoing, and optimistic.
Mally is thoughtful, solitary, and independent.
The twins think of themselves as one. They dream the same dreams, experience the same emotions, and even share a language nobody else can understand.
Then, on their 13th birthday, a mysterious fire nearly kills them both. Suddenly, they begin having strange visions - different visions - and the bond between them begins to unravel.
They discover that they have each been given a gift...But what they see in the visions they have of those closest to them could destroy their lives.
