David, Xander, and Toria King never know where the mysterious portals in their house will take them; past, present or future. They have battled gladiators and the German army, dodged soldiers on both sides of the Civil War, and jumped from the sinking Titanic
. They've also seen the stark future that awaits if they can't do something to change it-a destroyed city filled with mutant creatures.
And they've still got to find a way to bring Mom back and keep Takisdian from getting them out of the house. The dangers are hitting them like a whirlwind...but the answers are becoming apparent as well.
