Gregory — Grace Jelsnik

The first half of book 3 in the William Young series is narrated by Gregory. Everyone in Gregory's life has betrayed him: his parents, his beloved, his foster-siblings, and even his squad mates. Desperate to find his place in a hostile world, he sets off on his own. His journey in search of acceptance takes him from the wooded hills above Ashley, Wyoming, to the concrete mountains of Denver, Colorado, where he finds his one true love, the woman who will never turn on him. With Sasha by his side, he is prepared to exact vengeance on those who betrayed him.
Rachel narrates the second half of book 3. Having finally accepted that Billy will never return her feelings, he surprises her. However, Hoplites must meet Hydra in a battle to the death, and Billy, a pregnant Rachel, and a surprising warrior addition leave for Colorado, where they once again meet the man determined to kill Billy. In a stunning conclusion of the three-volume series, one of them suffers the greatest betrayal of all.
