Things aren't always as they seem...That's probably the first lesson to be learned as a member of Earth's elite Multinational Off-World Monitoring Agency. And it's a lesson that becomes a stark reality for MOMA agent Harper Reardon when she finds herself unexpectedly heading to the moon to investigate an international incident at the lunar colony. At first everything seems fairly straight-forward but Harper just can't get past the feeling that something is off. Something isn't exactly as it seems. So just what is it that's got her instincts waving the proverbial red flag? Is it something about the New Eden colony? The group of scientists she encounters while en route to the moon? The case itself? As her investigation begins to unfold, things get very complicated - and the game board is totally upended when a cataclysmic disaster threatens to leave her stranded some 239,000 miles from home! Determined to solve her first solo case - and get back to her husband and daughter on Earth - Harper faces the biggest challenges of her life and discovers whether she really has what it takes to tackle what's looming on that distant dark horizon.
