Escape from Harrizel - Arizal Wars, #1

Fallon is like every other Arrival brought to Harrizel - an alien planet restoring the human race after a fatal war left Earth in ruins. But once viewing the all-day work camps and the nightly, orgy-like atmosphere, Fallon suspects her hosts, the Dofinikes, might have a secret agenda of their own. With everything on a strict schedule and talking forbidden, Fallon makes up her mind to escape. Finding it's harder than she expected, hunger forces her to turn to the Market - an underground system run by two rival Clans.
It's after an unexpected excursion that she crosses paths with Reid, an ex-Clan member who seems to know more than he's letting on, especially why everyone is so eager to do everything he says. But with his newfound attention, the Clans have taken an interest in Fallon. The Dofinikes want more repopulating and with people going missing, time is running out. Fallon must solve the mystery of her rescue, and discover the truth behind Earth's ultimate demise, all while protecting her heart from the one man who could shatter it forever. Book 1
