Ren doesn't remember what happened five years ago.

She only knows what was lost. Not only her health, but her mother...

Now, Ren navigates life in her sleepy Scottish village through meticulously crafted plans and lists, ignoring the advice of her psychiatrist as she battles chronic pain no doctor can diagnose.

But Ren can't plan for everything. Not the strange, unruly weather, and not for the arrival of a cloaked stranger, shrouded in secrets and haloed by fireflies. Nor for his sword-weilding companion, who makes Ren feel more than a little...buzzed.

Not just sent to find Ren, but Collect her.

When the decision to leave the world Ren knows comes far sooner than it should, Ren must learn to adapt with no plan, or list. it might be the only way to both see her mother again, and save Ren's life.

But where answers linger in a place where magic dances across the skies, roams the land and swims the seas, so do those who want Ren, not for who she is, but what.
