Titan of the Stars (Book 1)

Alien meets The Titanic in this tense YA science fiction horror series by #1 New York Times bestselling author E.K. Johnston.
Celeste knows every inch of this ship. She's proud of her work as apprentice engineer. And as the maiden voyage of the Titan launches, she's optimistic for the promises of this new journey from Earth to Mars — this new life.
Dominic arrives at his suite where his valet is busy unpacking his things. His chest is tight, already feeling anxious inside his dad's precious new ship. Once it launches, he's trapped, inside the ship and inside the life his father has chosen for him — a life that will leave his dreams of art school behind.
Discovered under melted ice caps, ancient aliens have been brought onto the Titan as well, and stored in display cases for the entertainment of the passengers . . . until an act of sabotage releases them into the ship, with zero discrimination for class, decks or human life . . .
