The Eden Paradox — Barry Kirwan

A murder... a new planet mankind desperately needs... a thousand-year old conspiracy... What really awaits us on Eden? In a world beset by political turmoil, environmental collapse, and a predatory new religion, a recently discovered planet, Eden, is our last hope. But two missions have already failed to return. Blake and his crew lead the final attempt to bring back good news. Meanwhile back on Earth, Eden Mission analyst Micah Sanderson evades assassins, and tries to work out who he can trust, as he struggles in a race against time to unravel the Eden Paradox.
