Zenith Maelstrom knows he’s forgetting something… But he can’t quite remember what. He wakes up to notes in his handwriting with messages like, “Prepare for battle!” – but what battle? – and his sister Apogee seems to grow angrier with him by the day. It’s not until he finds Apogee sneaking back into the horrible bag hidden away in their basement that all the dreadful details about GrahBhag resurface. The spiderlike Shlurps. The trio of foul mouths that hunger for blood. Eldritch horrors around every corner. Desperate to save Apogee from her ill-planned attempt to right the wrongs of their last trip into the bag, Zenith is forced to follow her into the bizarre world that has certainly not forgotten them. Between old foes set on vengeance like Raggedy Albert and terrifying new ones like the haunting Wraith, Zenith will have to put things right with his sister without falling into the clutches of those who would do him harm. For if he is caught, Eternity Tower awaits...
