The lost island of Atlantis has returned—and humanity’s survival hangs by a thread.

Missing for millennia, the Oblivion Order’s most secret scientific base returns without warning, its experimental gravity engine unleashing catastrophic ripples through time and space. As the island’s uncontrolled presence begins to destabilise the moon’s orbit, the Earth inches closer to a fatal collision with the Sun.

Only their most elite time travellers can prevent global extinction. But salvation requires an unlikely partnership with the Syndicate, a dark guild that’s always operated outside the Order’s rigid rules.

With the moon’s trajectory shifting and global panic mounting, a desperate race against time begins. Some will fight to preserve humanity’s existence, while others have plans that run deeper than survival.

The seventh book in the bestselling Infinity Engines series, this twisting time travel adventure explores how the smallest actions can unravel—or remake—the entire universe.
