Doom Star (Time Surfers, No. 8)

The Time Surfers have got to find the photon crystal before it’s too late! The crystal has the power to change time: the present, the future—even the past! But Zoa, a slimy, slippery dronth, is hunting for the crystal too, using every power and ally she has at her disposal.

Who will get to the crystal first? And who will control the future?
