The Impossible Quest Books in Order

After attackers enslave the people of Wolfhaven Castle, four young survivors undertake a quest to awaken legendary warriors. Finding the magical ingredients required by an ancient prophecy means facing creatures and dangers for which none of them is prepared.

Fleeing Lord Mortlake, Tom, Quinn, Elanor and Sebastian follow a unicorn into the Witchwood. A blind witch offers help, but the children must decide whether to trust her while searching for creatures essential to saving Wolfhaven.

Having gathered the final ingredient of an ancient prophecy, four young companions return to Wolfhaven. They search the castle’s crypts for the sleeping warriors who could save their people, racing to complete the spell before the dark moon rises.

Escaping their pursuers, the four young companions continue south in search of magical creatures. While Sebastian and Elanor seek aid at Crowthorne Castle, Tom and Quinn enter a mysterious moor where a dangerous beast awaits.

With most of their quest completed, Quinn, Sebastian, Elanor and Tom still need a sea-serpent’s scale. Their journey to a submerged kingdom brings new dangers and revelations about the events that drove them from Wolfhaven.
