Penelope Williams continues her journey in the next installment of the Powerhouse Series . . .

At the Edge of the universe, the incursion created by the Kolvat only worsens. The fall of the Academy was only the beginning. The Kolvat were only the beginning. The Witches are losing the war.

A myth from the beginning of the universe provides a glimmer of hope: the Weapons forged by the Witches at the beginning of time could help to drive out the Kolvat. But no one has seen those Weapons in millennia. No one believes they're real anymore.

Back on Earth, Penelope Williams continues her work. Work on magic, work on her normal life, work on her freedom. While living with the mother who disowned her, she feels trapped and claustrophobic, no longer allowed to travel where or when she wants. But she is given the task of finding one of the Weapons, rumored to have been hidden in Earth's galaxy for the past several millennia.

A stunning discovery changes everything as a new enemy encroaches on their universe from the outside. The devouring of reality at the Edge of the universe changes the focus of the war. How can they hope to defeat an enemy that can consume reality itself?

Between the rise of this new enemy and her own personal problems, Penelope barely has time to think. She focuses on her quest to find the Weapon and bring an end to the Kolvat. In the process Penelope finds herself trusting an unexpected person. But is that trust misplaced? And will she ultimately regret letting her secrets out?

In this sequel to Altair, follow Penelope as she seeks the lost Weapon, tests the limits of her freedom, and adjusts to the changing nature of friendship.
