In the third book of Leo's Map of Monsters series, Leo's village is set to celebrate their yearly Spring festival, a night of festivities filled with food, games, dancing and singing. Leo is especially excited because Henrik gave him the night off so he could attend with his best friend Jacob. That is until the village chief, Gilda arrives and tells him he is desperately needed once again to save their village from an encroaching monster. Swiftly Leo tells a little white lie to Jacob and heads out for the Guardians cabin in the woods, unbeknown to him he is being followed. Leo is given his next assignment to capture the Grass Gulper, who is making its way toward their village. Unfortunately, he will only have one chance to capture it, as he only has one Shrinking Stone left, so he will need to make sure that his shot counts. Assisting Leo once again is Starla, a leatherwing who has the unique ability of communicating her thoughts directly into Leo's head. And as a new surprise, Leo discovers that he was followed by none other than Jacob, who is injured when the Grass Gulper attacks. Seeing this as an opportunity to work with his friend hunting monsters, Leo hopes that Henrik will train Jacob too, but can they trust him with this secret? Or must he resort to taking a hair from the legendary Frightmare's tail in order to take away Jacob's memories of being in the forest for good?
Seeing this as his only option, Leo agrees to hunt down the Frightmare, but getting a hair from the Frightmare's tail is more difficult than you would think. They can disappear at will, making it challenging to get a shot off in time. They're also enveloped in blue flames and fog which makes it difficult to approach them. They're aggressive and vehemently protective of their territory. Plus, their mighty hoofbeats are frightening, especially when they come charging at you during an attack. Hoping to escape just those attacks, Leo ventures into the ruins surrounding the Frightmare's domain only to find himself in a very dark space, which truthfully was unnerving. Leo certainly had his hands full in this story. I'd say this was his most dangerous mission yet and exemplifies just how brave Leo is.
