“Castro sheds light on the past and nature of the aptly named Gloom mansion […] spooky!”
“Adam-Troy Castro [...] holds an exquisite imagination and brings a nightmarish world to life in the Gustav Gloom series.”
“There’s pretty much nothing not to love about a mansion filled with endlessly spooky rooms, shadows with minds (and appetites) of their own, and sweet characters with dark secrets.”
“This is an amazing book. And if you still haven’t read the first one, you need to do so right away. Because Gustav Gloom is such an amazing person, and you will all fall in love with him.”
“The paranormal aspects are well-done but not over-done, and there’s enough of an overarching plot to assure readers that this isn’t a series full of one-shot adventures. And so I hereby proclaim middle-grade paranormal to be the next big trend.”
"Fun fast read. I love Fernie and Gustav and the dynamic they have together"
