Aestus

An underground city, built centuries ago to ride out the devastating heat. A society under attack. And a young solar engineer whose skills may be the key to saving her city...if she doesn't get herself killed first.

When Jossey was ten, the creatures of the aboveground took her brother and left her for dead, with horrible scars. Now, years later, she's a successful solar engineer, working to keep her underground city's power running, but she's never really recovered. After she saves dozens of people during a second attack, she is offered a top-secret assignment as a field Engineer with Patrol, but fear prevents her from taking it...until Patrol finds bones near where her brother disappeared.

She signs on and finds herself catapulted into a world that is far more dangerous, and requires far more of her, than she ever imagined. The creatures and the burning heat aboveground are not the only threats facing the City, and what she learns during her assignment could cost her her life: one of the greatest threats to the City may in fact lie within. With thousands of lives at stake, can she act in time?
