Summary of Emily Jayne and the Kairos Codex: Eleven-year-old Emily Jayne (EmJ) Hutchings knows aliens exist. She's as certain about that as she is about the Fibonacci series and the digits of pi. Her best friend and adopted cousin, Sarah, is an alien camouflaged as a human. EmJ is surrounded by mysteries: her canine sister Rex is much smarter than any dog should be; her friend Samuel vanishes without a trace from the schoolyard; and Sarah's planet of origin is unknown. But Sarah is sick and needs help from her own kind. Can EmJ and Rex find Samuel? Will EmJ be able to find Sarah's people before it's too late? EmJ and Sarah invent and build an interstellar communicator and send a coded invitation toward the star Epsilon Eridani. Two weeks later, Cindy, a friendly 11-year-old alien appears in EmJ's backyard. EmJ hopes that Cindy and the scientists from her planet can help track down Sarah's species. The three friends and Rex are ready for an epic adventure. But bad luck comes in threes. They're abducted by time travelling aliens. They discover that they're at the centre of an interstellar war. And EmJ only makes things worse when she steals a crucial artefact from the enemy. The Kairos Codex. It's from the future. It commands their capture. The fate of worlds hangs in the balance
