Aster, a biology student struck with terminal cancer and at the end of her life, finds herself thrust into a new world. The universe passed a threshold, and it was time to finally be integrated into the vast multiverse; an existence where the only one you can rely on is yourself. Flung into a tutorial filled with dangers and opportunities—into a world that should breed fear and concern, an environment that brings the worst out of most—Aster instead finds a life she never knew she’d been meant for all along.
