Paranormal YA romance books?

[Maxie]

Can anyone recommend a YA romance novel with paranormal or supernatural elements?

Something like "The Ghost of Buxton Manor" by Jonathan L Ferrara 
(about a ghost boy trapped in his childhood home that falls in love with a human boy that moves in)
or "Teeth" by Hannah Moskowitz 
(About a boy that travels to an island with his family to cure his sick brother, but ends up meeting a damaged 'fish boy')
or even something like The Raven Cycle by Maggie Stiefvater
(which I cannot describe sufficiently in a sentence and for that I apologise.)
It doesn't have to be all romance- it can just have romance in it.
I just love books with supernatural characters, things like Ghosts, Merpeople, Vampires/Demons (not Twilight) and others. 
​Any recommendations?
