Eep...the adventure begins! Raven Boy has short black spiky hair, amazing night vision and can talk to animals. Elf Girl is light of foot, sharp of mind and...elfish all over. Together they have strange, creepy, altogether spooky and hilarious adventures as they save their world from trolls, ogres, witches and things that slither and slide in the fiendish forest.

Saving the world isn't going very well for Elf Girl and Raven Boy. They've left Fright Forest and crossed a huge plain to the worryingly named Monster Mountains, where they find a sign telling them to turn back. Perhaps they should do as it says!

Elf Girl and Raven Boy have survived Monster Mountains and arrived on the shores of Scream Sea. Kidnapped by Scrim, pirate captain of the Naughty Porpoise, they're held prisoner below decks as the ship sets sail. But Captain Scrim and his crew are even more interested in mermaids than in bird boys and pointy-eared girls, and when they capture one they throw the pirate party of a lifetime. Our daring duo, plus Rat and mermaid Molo, escape and go their separate ways, but not before Molo has given Raven Boy a tiny shell on a silver chain and told him to call on her for help. They continue their search for the Goblin King with adventures on a desert island, an 'invisible' spell, encounters with an even worse pirate called Blackblood on the stormy high seas, and then below the waves with the many scary beasts and monsters that roam the deep. No one said saving the world was easy!

Elf Girl and Raven Boy get hot and bothered in the desert as they come a few steps (with sand in their shoes) closer to finding the Singing Sword and the Tears of the Moon. They bump into a grumpy camel, a grumpier genie, Sultanas, Sandpeople and scorpions as they try to save the world from the Goblin King.

Terror Town is trouble with a capital T. What will happen to our intrepid trio (that includes Rat) when the Tears of the Moon are taken, and Terrible Tim and the Trolls are on their trail? There are tempers (Elf Girl's), tests (for Raven Boy), tunes (the Singing Sword's), oh and zombies, with a capital Z, too.

Eep ...The final adventure awaits! Nothing can stand in the way of Elf Girl and Raven Boy saving the world...Well, almost nothing. Just a sea monster, a dragon, and rivers of molten lava. Not to mention some seriously Creepy Caves. Defeating the Goblin King might be harder than they thought. The sixth laugh-out-loud adventure from BLUE PETER BOOK AWARD-shortlisted Marcus Sedgwick and Pete Williamson.
