Hunting the Merrow (The Merrow Trilogy #2) by Heather Rigney ★★☆☆☆

Gruesome, brutal, and bleak.

Lots of rape and slaughter.

With a hopeless ending. 

Why? Why? Why?!?!

Waking the Merrow (The Merrow Trilogy #1) by Heather Rigney ★★★★☆

"They were the wide eyes of her aquatic cousins, unmistakable with the unnaturally large eye-sockets and light-colored irises. He was a merrow." 

Secrets at Midnight (Psy-Changeling #12.5) by Nalini Singh ★★★★★

I do not read books looking to cry but sometimes great authors, like Nalini Singh, just sneak one by me. 

Into the Gray by Margaret Killjoy ★★★★☆

"We’re not the same," she told me. "It’s not possible for us to lead the same life." 

Beautiful trans thief falls madly in love with a mermaid, a hungry mermaid. With a love Laria understands is obsession, they lead evil men to die in the Waking Waters.
