'Death is a lot of damned work,' thinks 18 year old ghost, Charlotte Williams, as she braves the unsettled world of the In-Between. It's here the rebellious teen finds the clues she so desperately needs in her battle against diabolic, secret society, The Hollow (who took her life, and just happen to be trying to end the world!).

Upon her return to the 'Bone Yard' (aka Crystal Springs Cemetery), Charlotte meets up with 20-something supernatural bestie, Poe, an acerbic goth who works with her to decipher the latest clues. Fellow ghost, Poe is something of a big sister to Charlotte; strong, hilarious - and always full of secrets. Though Charlotte's already been dead several years, Poe, on the other hand, may be as old as time! As past victims of The Hollow, both are now intensely dedicated to stop the evil sect, who chillingly view human existence as a 'failed experiment'.

After several fraught run-ins with 'the Devil's janitors' (as Poe calls them), Charlotte is devastated when The Hollow kidnap her young son, Luke, in retaliation. Charlotte then suffers with the guilt of screwing up his young life 'even in death', before forming a plan with Poe to get him back - and make The Hollow pay.

Ultimately, Charlotte and Poe are forced to cosmically separate in their search for Luke. However, in doing so, they're both severely tested and must grapple with their limitations - and their own dark pasts. Along the way, we meet a string of colorful characters both in 'Hollow Land' and the All-American (or is it?) Crystal Springs - and maybe even save the world.
