Summary
fathomless / ˈfaT͟Həmləs / adjective – unable to be measure or understood, extremely deep
Wally never expected to come back to Happy Harbor. Not after his near drowning in the sea caves by his childhood home — which inevitably led to his parents’ divorce. But here he was twelve years later, fresh out of grad -school and moving back into his late father’s old house.
A summer spent in the sleepy town he grew up in on the Rhode Island coast should have been idyllic. A quiet three months working in his uncle’s aquarium as he figured out what the hell he wanted to do with his life. But, it turns out, finding a siren tangled in a fishing net at the bottom of the bay would only be the beginning of his troubles.
What happened to the poor Nereid who now haunted Wally’s thoughts? Why couldn’t he shake the feeling that their fates were more tangled than the net he’d cut away from its beautiful tail? And who was the so-called expert called in by the counties Game-Warden to investigate the new predator making waves in the Rhode Island Sound?
The further Wally dug, the deeper the mystery took him — and someone had swim to the bottom of it.
Good thing Wally has his diving license.

Summary
After the events of Good Things Come.
Astarion and Tav have solidified their roles in the Underdark with the other Spawn, as well as in Faerun. They realize there is still much more they can do to stop another Vampire lord, and help another of their Companions in the process.
A snippet of things to come:
Except Tav beat Astarion there and reached him first, and a wet SMACK sounded as Astarion's chest collided with her shoulder blades where she stood solidly between them.
For a moment, Astarion only saw red.
For a moment, Astarion heard nothing but the roaring, rushing sounds in his adept ears - that of the rolling sea, and Tav's blood catapulting through her arteries with her own anger.
Astarion's eyes focused and traced her form and up her extended arm, his lip twitching with the beginning of a snarl at the action that had been denied him, but the scent of Gale's blood hit his nose then. The odor was strong despite the pervading smell of salt in the surf that lapped along the shore at their feet.

Summary
The stories say a siren's song is to be feared. They call it a curse, a death sentence.
They are wrong. The song is simply a beginning. The real danger is far softer, slower, and sweeter, a doom borne upon the siren's kiss.
Whatever the truth, Viktor has no cause for concern.
For what would a siren want from a broken man like him, fleeing a lonely life in Piltover to another by the sea?

Summary
“What do you want from me, Raphael?”
Raphael’s smile was slow and in tandem with the straightening of his spine. His sun-browned hands positioned themselves behind his back.
“I have asked myself that very question over and over again, thinking the answer haunting me could not be such a simple thing. It could not be rooted in such base instinct. Perhaps amidst the chaos of that fateful day, you managed to charm me. But I cannot deny what I am, Astarion, and what I can and cannot resist. The answer is always you. I want you.”
—
Astarion suffered many constants at the aquarium: constant boredom, constant awestruck faces pressing against the glass, constant hunger, constant dread of what torment Cazador would bring next…and the constant appearance of the handsome man he had saved four decades ago. The same man that shook hands with Cazador. A man that wasn’t a man at all. -
