The girls of Spirit Service get involved in a heated competition with a rival, all-boy group in this second book in the sweet and spooky Spirit Service middle grade series that's Ghostbusters meets The Baby-Sitters Club. Spirit Service is booming, and with "Holloween" night approaching, guiding spirits to the afterlife has never been easier. But all is not well. Raveena Gill and her besties have come across an impossible creation: another phantom phone! Worse, this phone belongs to a boys-only group of paranormal fanatics, and the boys seem bent on using its darker abilities to trap spirits for their own gains. To keep the copycat phone out of the boys' hands, Raveena proposes a wager. The first to vanquish fifty spirits by Holloween will get to keep both phones. If Raveena fails, she'll lose Spirit Service; if she succeeds, she'll stop the twin phone from being used for evil. As tensions between and within the clubs rise, a sinister threat stirs in the shadows. To stop it, they will have to band together to uncover the darker origins of the phones themselves...and this time, both the lands of the living and the dead are at stake.
