This is of course my opinion but I think this book felt like a practice in listing a haunted house that had all the worst things you could think of and that was mostly it. 

I know the point is power in love and relationships but I found the characters didn't have much personality outside of their trauma.

 I didn't hate it for sure but I'd say if the idea of an eerie never ending maze is the element you like House of Leaves does that better and if the relationships of adults with trauma coming back together after years apart in an unsettling setting is what you enjoyed Mister Magic does THAT better. 

Anyway just fine but if you love a series of nightmare haunted house rooms being described at you on a loop you'll love it.
