Hornsby & Halo (Hornsby & Halo #8)

Talk about heavy! The super-stressed-out Rose and Zach have learned their true heritage after taking their road trip to Heaven and Hell. To make matters worse, they've been cast in the school play of Paradise Lost with Rose playing an angel and Zach a devil. Meanwhile, the rogue elements of Heaven and Hell plot against the kids’ spiritual guardian, the Adjudicator, a dreaded threat. Who - and what - are the Hollowed Ones?
