RHIDAUNA, The Shadow of the Revenaunt, Book 1

'Rhidauna', the first book of the great fantasy series 'The Shadow of the Revenaunt'.

The night before his Coming-of-Age, Ghyll and his two friends escape their castle on a clandestine boar hunt that will forever change their lives.
The hunt proves a disaster, and with one of them badly wounded, they return just in time to see their island castle destroyed by macabre warriors from a dragon boat, and by flocks of fire-breathing birds. Ghyll's eighteenth birthday turns into a nightmare as they flee into the night.

Now begins an epic journey to find out who is trying to kill them - and most importantly, why?

Fortunately, they can count on the help of new friends, including a sometimes overly enthusiastic fire mage, an inexperienced paladin and a young beastmistress who is also a ferocious mountain lioness.
It soon becomes clear that not one but several sorcerers want to kill them. Are those blackrobes really followers of a terrible, long-forgotten organization?

And whose cold hand reaches across the boundaries of space and time to crush weakened Rhidauna?
