Important:
The blurb for Fathoms Deep contains major spoilers for those who haven't read Blood Shadow (and the Eye of the Storm series that precedes it).
Go to Blood Shadow
Go to Eye of the Storm
Despite its character link to the Eye of the Storm series, this novel is a separate entity from that series and does not refer to it in any depth. However, Blood Shadow is necessary to read to know how Laura and Roman ended up in Fathoms Deep, therefore this is referred to as "A Blood Shadow Novel".

FATHOMS DEEP

A Blood Shadow Novel
Obscured by mythology and buried by aristocracy, an ancient secret festers...
Amid the white-washed houses that decorate the beautiful island of Santorini, Greece, lies an ancient secret that will pull Laura and Roman fathoms deep into an atrocity obscured by mythology, and buried by aristocracy...

Laura is half-werewolf and half-siren, made 'siren' accidentally by the human male who saved her life five years ago with his breath of life – his siren breath.

Roman Dalton is human, and the only known male to carry the siren gene. Although he cannot fully form into his aquatic counterpart, he suffers the torturous effects of his compromised DNA every full moon when the tides are high - effects which have been steadily growing worse.

Posing as man and wife, and battling their own villainous shadows from a past best left drowned, the reluctant couple find themselves in Santorini, about to embark on a deadly mission to uncover more about the elusive siren in the hopes of finding a cure. For Roman was never meant to carry the siren gene, and certainly never meant to pass it on to a she-wolf.

Their answers might dwell among the vegetation of the monastic Mount Athos...

But there are people – very important people – who would rather some secrets remain hidden forever.

If Laura and Roman make it to Mount Athos, they may never make it back out.
