Island of Secrets

I'm a paranormal investigator without a home of my own. So when a wealthy
client offers me a lucrative job on a private South Pacific island, I jump at the
opportunity. It's not all fun in the sun, though. A dead merman - no, really - with an
arrow in his chest has washed up on shore. My investigation reveals a century-old war
between the mers and a goblin tribe, who believe the mers stole their treasure. But the
real thief was a pirate! He buried the treasure and died before digging it up again.
Casper, my guardian angel and sort-of-but-not-really boy-friend, usually helps me out
but he's acting all weird and busy. The only person left who can help me find the
treasure is the pirate's former girlfriend, who happens to be a forgetful, alcoholic
ghost. Oh, and I'm not the only one searching for this treasure. Someone else wants it
badly and they're prepared to commit murder to prevent anyone else from getting
it…
