The year is 1981. Sister June has been sent on her greatest – and most uncomfortable – assignment yet. The First Order want her to visit an archaeological dig deep in the African desert, where an eccentric English explorer claims to have discovered a tomb from a lost civilization.

Hopelessly out of her comfort zone, June quickly discovers that Mortimer Weaver isn't just eccentric – he might actually be dangerous. Digging deep beneath the desert, Weaver has certainly found something, but does he know more than he's letting on? As strange noises terrify the makeshift desert camp at night, June starts to worry that they might be about to disturb something that's better left well alone.

The Fifth Tomb is the fifth book in the Chronicles of Sister June series. Readers are advised to start with the first book.
