Enzo Cruz was raised to destroy the system. Maddie Westing was born to inherit it. Together, they'll have to burn it all down to save what matters.

The complete Against the Red Sky duology — Mission X and Colony Exposed, together.

Mission X (Book 1): Enzo is Terra Primera's youngest operative, sent to infiltrate the Mars Ascendance Academy, sabotage the shuttle, and disappear. Maddie is one of thirty elite students chasing her dream of reaching Mars and her mother. Exposing Transcendia founder Augustus Sardeth costs them their freedom.

Colony Exposed (Book 2): Enzo and his friends are sent to Mars to die building domes they'll never live in. Maddie has to break out of her uncle's facility and reach Mars before it's too late — only to find a colony built on a secret darker than either of them imagined.

Bundle price: $7.99. Signed copies bundle for $15.99.

Both books are out now and delivered instantly by BookFunnel.

2026 Quarterfinalist, BookLife Prize in Fiction

2026 BookLife Prize Quarterfinalist · 9.75 out of 10

“Illarmo is a natural storyteller, developing polished, smooth prose that builds a creeping dread along with nail-biting suspense.”

“Mars feels like a tangible place here, built on rigid systems and orders enforced by guards, prison labor... Forced labor on Mars is a chilling premise, and the experiences Illarmo’s characters undergo are vividly real.”

Perfect scores for Plot, Prose and Character. Reviewed by The BookLife Prize, a Publishers Weekly property.

  • Nick Wilford ★★★★★

    "One of the best YA sci-fi tales I have read in some time. The book keeps up a lively pace throughout and is easy to read quickly."

  • ★★★★★

    "I just finished reading Colony Exposed and I think this one was better than the first book, it picked me up and took me on a thrill ride from beginning to end, and the end was the best part!"

    Early reader, Colony Exposed

  • ★★★★★

    "This was an absolutely perfect conclusion to the Against the Red Sky saga. More action packed than the first, the character development was stellar all the way through."

Does the story actually end, or is there another cliffhanger?

How do I get the map of the Mars colony?

The map of the Mars colony is part of the book itself in the signed hardcover editions (the Special Edition and the Book Box), bound into the interior rather than tucked in loose.
