CloudWorld

"Thrillingly dramatic, a heart-pumping tale set in a vividly-imagined world." - William Nicholson (Oscar-nominated screenwriter of Shadowlands and Gladiator)
CloudWorldis set on a planet entirely covered in a thick cloud layer. Mountain peaks - thousands of miles apart - rise out of the clouds, their gentle slopes covered in fields and orchards. Many of these peaks also have huge, populous citadels on them.
The cloud-dwellers are not aware that they live on mountains and the cloud depths are an abiding mystery; many believe that they are the realm of Omnium, a divine being who created them.

At the beginning of the story, the king of one of the citadels - Heliopolis ('city of the sun') - fails to return from a diplomatic visit to a neighboring citadel, Selenopolis ('city of the moon.') He is presumed lost in the cloud depths. His son, Marcus, who lives a sheltered but lonely palace life, insists that a mission across the cloudscape be staged in search of the king. But Marcus realizes too late that there is conspiracy in the citadel. Someone wants him dead and he is plunged into a terrifying new adventure beneath the clouds.
Marcus and his comrades discover that, whatever its true nature, some mysterious force seems to bind their world together, making it habitable both above and below the clouds yet keeping the two regions apart. They find themselves in a more ancient, less evolved place called Daldriadh. Its inhabitants have created a whole religion based around debris fallen through the clouds over many centuries. They are perpetually at odds with one another, but also determined not to be colonized.
Marcus has to not only survive in this world, but also win the trust of the races who live there and find a way of getting home...
