Saved a dolphin. Lost her memory. Now they're after her.

When rescuing a dolphin calf leaves marine park owner, Keiko, aka KK, with amnesia, she can't escape the mysteries swirling beneath the surface any more than she can outrun the escalating violence targeting her, the orphaned mammal, and her family's ocean sanctuary.

With her hazy memory, KK can't ID the poachers, yet they seem to know her?and their continued threats fall on deaf ears as if the police don't believe the dolphin killers actually exist due to her foggy recollections.

To make matters worse, animal control officers ruthlessly push for euthanizing the rescued dolphin calf; as they seem to have forgotten that poaching is the real crime here.

KK is no pushover and with friends' help, she'll continue to expand her parents' legacy despite a new chilling message found in her sanctuary, bearing the signature of a person she had prayed never to encounter again.

Now only her memory holds the key to why saving a dolphin made her the next target.
