Star Riders: Transhuman — Tony Bedard

A brilliant ex-NASA rocket scientist shatters the solar system with a breakthrough no one was ready for—his equations igniting a catastrophe that leaves humanity on the brink of extinction. Now, his two sons must rise from the ashes to lead the desperate fight to reclaim what was lost. To defeat a ruthless alien empire bent on total domination, they must finish their father’s revolutionary work on time travel—and master the secrets of the universe itself. But time is no straight line. Their journey began long before they realized it—in a distant corner of the cosmos, where past and future collide. TRANSHUMAN is a sprawling saga of evolution and transcendence—where science, technology, and sheer human will push the boundaries of what it means to be human. To survive, the brothers must face their deepest selves, unlock their place in the cosmos, and grasp the fragile quantum thread that holds reality and humanity together.
