Hive, by AJ Betts

Beekeeper Hayley lives in an underground religious commune organised by rigid rules and roles. Gardeners marry netters and their children are raised as Enginers. The only child who follows its parent is the son or daughter of the Judge, who oversees the community. Although largely content among the gardeners, Hayley keeps a secret from all but her best friend. She suffers from the head pains that may presage the onset of madness and ostracism. A sudden death leads Hayley to question her community and her place within it and she will need help from an unlikely source to find her way forward. A few holes in the structure are glossed over by a fast pace and an appealing and courageous heroine. A rush of exposition is needed to push through to the climax, but a neat cliff-hanger paves the way for the sequel.
