Sometimes adventure knocks. Other times, it kicks the door in.

"Dearest Alexandria and Ozymandias,

If you are reading this, I have perished. My demise likely involved some manner of spiked pit or curiously fanged beast, so it's doubtful I suffered long. Do not try to find me - the path is too perilous, and I am lost to the mortal plane."

When Alex and Ozzie read their grandfather's latest "death" letter, they barely blink. Dying six times in two years has to be a record, even for an explorer as incompetent as Sir Quidby Forsythe III.

Faster than you can say "kidnapped by a giant, glowing lizard," the Forsythe twins are dragged into a world of ancient prophecies, sarcastic swords of legend, mutant slime beasts, and a growing awareness their grandfather might be the greatest explorer in history.

With Skhaar the Annihilator hot on their trail, Ozzie and Alex must solve the mystery of Sir Quidby's disappearance before they become the final victims of the Forsythe Curse.
