The series follows the story of the 12 year old Tom as he ventures out from his village on a quest against evil.

At the start of the first series of novels the King of Avantia, King Hugo, invites Tom to embark on a quest to free the kingdom from the evil curses placed upon the Beasts that protect it. With his trusted companion, Elenna, Tom travels across Avantia, guided by a magic map. Accompanied by Storm, a jet-black stallion and a faithful wolf named Silver, the two of them face the biggest adventures of their lives. Together they set out to defeat the evil wizard Malvel and free the kingdom.

Tom's catchphrase, which is repeated in every single Beast Quest book published to date is: "While there's blood in my veins..." then whatever his specific mission is after it.

The fictional world of Beast Quest is divided between several kingdoms.

An evil Wizard, Malvel has enchanted the 6 magical Beasts of Avantia – only a true hero can free the Beasts and stop them from destroying the land. Is Tom the hero Avantia has been waiting for?

The evil Wizard, Malvel, has stolen the magical suit of golden armour and scattered it throughout Avantia. With help from Elenna, Tom vows to find the pieces – but they are guarded by six terrifying new Beasts! Can Tom do it?

Tom and Elenna must travel to Gorgonia to rescue Avantia's good beasts, but each one is guarded by an evil beast. Torgor guards Tagus, Skor guards Epos, Narga guards Sepron, Kaymon guards Nanook, Tusk guards Ferno and Sting guards Arcta. To free the Beasts, Tom journeys into the sinister Dark Realm…

Taladon the Swift has returned! But to Tom’s horror, his father is a ghost. To save Taladon, Tom must battle the Ghost Beasts and collect the pieces of the shattered Amulet of Avantia. The Beasts live in the Forbidden Land, located in Avantia's east.

Tom and Elenna must travel to Gwildor, Avantia's twin land, to free its beasts from evil wizard Velmal. In this series Tom meets Freya, Mistress of the Beasts, who we discover to be his mother! To release her from her curse, placed on her by Velmal, Gwildor's Dark Wizard, Tom must defeat the ferocious Beasts that guard the pieces of Freya's crown.

Tom's most challenging Quest awaits! For him to save his mother, Freya, Tom must travel to Kayonia to find six potion ingredients to restore her to full health. But each ingredient is guarded by a terrifying Beast. Komodo's black cactus, Muro's jade ring, Fang's red jewel, Murk's vines, Terra's white flower & Vespick's barbed sting are the potion ingredients.
