Caliban’s War by James S A Corey (Orbit £13.99) is book two of The Expanse, available later this month. Book one, Leviathan Wakes, was published in June 2011.
“While Earth and Mars have stopped shooting each other, the core alliance is shattered. The outer planets and the Belt are uncertain in their new – possibly temporary – autonomy. Then, on one of Jupiter’s moons, a single super-soldier attacks, slaughtering soldiers of Earth and Mars indiscriminately and reigniting the war. The race is on to discover whether this is the vanguard of an alien army, or if the danger lies closer to home.”
