A science fiction adventure about friendship, found family, and turning flaws into strengths. In a matter of days, humanity was wiped out by an oceanic parasite. Only Indi and 99 other children survived, plucked up by a neighboring alien species. It is Indi's duty to train in battle school so he can one day help his friends retake their homeworld. However, the standards to become a soldier are high. Those deemed too weak or cowardly will be put in cryo-sleep until Earth is safe for repopulation. As Indi ages and struggles to overcome his anxiety, he begins to suspect things may not be as they seem. The strongest kids in the group are being weeded out while the weak students like him remain. It's up to him to figure out what exactly is going on before his friends meet their end. A great read for fans of Ender's Game or Brandon Sanderson's Skyward .
