Godfall by Van Jensen (Bantam, £20)
The debut novel by a popular comic-book writer is set in a small town in Nebraska, after the landing of a three-mile-long alien figure dubbed “the Giant”. Local sheriff David Blunt is struggling to do his job following the sudden boom in population: in addition to scientists, government agents and soldiers at the highly classified research area established around the mystery from outer space, many more enthusiasts flood to the town, possibly including a serial killer. Two people have been killed in a horrifically brutal way when the FBI takes over and tries to shut him out. But when the next victim is a man he’s known all his life, Blunt is more determined than ever to catch the killer. His investigation draws him to infiltrate a doomsday cult and to discover more about the tangled lives of the people he grew up with, along with the possibility that there could be a clue in the physical composition of the Giant. A suspenseful, well-written blend of science fiction and serial killer thriller.

The Salt Bind by Rebecca Ferrier (Renegade, £18.99)
In 1770s Cornwall, Kensa’s father was hanged as a smuggler, and she now feels a despised outsider, especially in contrast to her quiet half-sister. Only when the local wise woman, Isolde, accepts Kensa as her apprentice can she imagine a future in which she could be respected as a healer. But there’s more than useful potions and a helpful dose of trickery to the role: the wise women of Cornwall are responsible for making sure an ancient pact between land-dwellers and the creatures of the sea continues to hold. Kensa has learned little of the Old Ways when she must suddenly act alone. She has seen Isolde summon the Father of Storms from under the sea, but when she does the same, she finds she has made a horrifying bargain. If she can’t put things right, the sea will rise and drown the whole area. A moving exploration of sisterhood and community, this is an evocatively written folkloric fantasy.
