Court of Twilight by Mareth Griffith

She's found a great place to rent.  She has a roommate who loves plants and never goes out if she can help it.  It's in a good area of town, she doesn't mind doing her shopping and the rent is cheap.  So Demi is a bit weird.  Most people are.

Parvus Press and Net Galley allowed me to read this book for review (thank you).  It is being published today.

It's when Demi goes missing and she finds an odd man in the flower box that Ivy realizes Demi might be more than a little weird.  The police don't care she's missing.  If anyone is going to find her, it will need to be Ivy.  Where could she have gone?  She decides to check out her computer and cellphone and see what she can find out...

What she finds is that she can see people other people can't.  It's not that they are ghosts; it's that they are other worldly.  They are almost like the fae.  You can't eat their food, you can't touch them or you'll disappear, too, and they have some strange habits.  Each year, someone is chosen as King.  After their year of holding the position ends, someone from the ancient past comes forward and kills the King.  Only one person has ever avoided that responsibility and he won't tell how it happened.  I don't think he even knows how it happened.

Ivy is trying to save Demi.  Everyone says she can't.  Almost by accident, she does.  But at best, all that does is give them another year to try to find a way to keep Demi alive...
