Scott Westerfeld’s Horizon series ran for five books between 2017 and 2019. It opens with Horizon and Deadzone, both from 2017, followed by A Warp in Time and Apex Predator in 2018. The final installment, Liferaft, closed out the series in 2019. The titles alone hint at a progression from exploration (Horizon) through danger (Deadzone, Apex Predator) to survival (Liferaft).
The books should be read in numbered order, since each picks up where the last left off. With two books released per year in 2017 and 2018, readers who find the series now can move through it at a steady pace without any long waits between entries.
