The Mayan UFO Code

Iris Blackwood and the Mayan UFO Code is the third release of the Mystery Detective series from IF/THEN Books.

Iris Blackwood Mystery Adventures · Book 3

Iris has left the island!

The case that takes Iris off the island — and into territory stranger than anything Saint Hyde has ever thrown at her. Ancient codes, modern conspiracies, and a mystery that might be older than anyone alive.

The Mayan UFO Code is the third book in the Iris Blackwood Mystery Adventures — interactive detective fiction where you choose what Iris does next. This one skews stranger, reaches further, and asks Iris to trust her instincts in situations where the rules in her Detective Notepad don't quite apply.

19 different endings. Five achievement levels. For readers ages 10–14 who are ready for a mystery that bends the genre.
