Another fan of Betovering House, yes! 
I’d be so happy to see an update, but I hope the author is doing fine…
As for other WIPs that I think are underrated…
I’m not sure if The Caged Songbird would count as being underrated (with the replies count and all) but gosh I’m putting it on this list because the WIP has amazing characters and needs more fans. Also the character driven plot is intriguing and MC is just precious. Okay, I’ll stop gushing now.
Welcome to the Circus is another one. I don’t know why, but I love creepy circuses that may or may not kill us. Also apparently I like to scare myself with clowns. Shame that there’s not a lot in the demo and well…seems like updates have stopped. Still a cool concept though!
Bad Penmanship for sure. With detective games being pretty popular (Wayhaven I’m looking at you! Of course the series deserves the love 
) I’m surprised this WIP didn’t become more popular? I’ll always have a soft spot for this WIP and Keys.
I may or may not edit later? If I can think of more…
