An eerie debut suspense novel that explores how little one man may know his own brother --- and his own mind.

The Maguire brothers each have their own driving, single-minded obsession. For Jonathan, it is his magnificent, talented and desirable wife, Harriet. For Roger, it is the elaborate universe he has constructed in a shed in their parents' garden, populated by millions of tiny insects.

Roger is known to all as a loving, protective, yet simple man, but the ever-growing complexity of the insect farm suggests that he is capable of far more than anyone believes. Following a series of strange and disturbing incidents, Jonathan begins to question every story he has ever been told about his brother --- and if he has so completely misjudged Roger's mind, what else might he have overlooked about his family, and himself?
