A city threatened by an ancient plague. A love across borders. A desperate choice that could break their worlds apart forever.

When a fragment of a deadly map is recovered from a medieval plague pit in London, the Mapwalker team must cross over into the Borderlands, once more. In a race against time, they must find the remaining pieces of the map in a journey across long-lost cities before the Shadow cartographers wield it against Earthside in a devastating attack.

Can Sienna resist the call of the Shadow as she struggles to save her home? Will Finn take a risk on love across borders or leave the Earthsiders to their fate?

Map of Plagues is book two in the Mapwalker Fantasy Adventure trilogy.
