4 Stars
Format: Paperback
This is a shifter romance that features a non-binary wolf whose father, an Alpha, is stuck in the old ways of running a pack. In comes Heather, featured within the previous installment of the series, who doubts herself and has self-hatred due to her strained relationship with her mother. There are werewolves, witches, dominants and submissives. It's a slow building romance at first and then full steam ahead. For those who are triggered by self-doubt, you may want to pass this up as well as those who hate the mention of the phrase mate or my mate. It is a good second installment of the series with enough open ended content to have a third book on the horizon.

A ghost story with tons of heart
Format: Hardcover
On the surface, this is a story about two kids ghost hunting in the Appalachian woods. But in reality, it's a beautifully nuanced exploration of loving (but messy) families, opening up to those you love, kindling new friendships, cherishing and protecting the environment, facing challenging emotions head on, and so much more. I'm so grateful that highly sensitive children (and adults) will get to know this empathetic, peace-keeping main character. There are so many protagonists that save the day with their heroics, but bravery so much more often looks like Tennie. This book serves as a beautiful reminder for those of us constantly filling others' buckets that our own needs and wants matter too.

Delightful spooky middle grade
Format: Hardcover
I was thrilled to learn that Ash Van Otterloo was releasing a second spooky middle grade set in Howler's Hollow. Instead of the zombies we find in Cattywampus, this book stars a girl who can release memories and, it turns out, ghosts from objects. She needs to figure out what the ghosts are trying to tell her before it's too late.

Good middle-grade fantasy/mystery
Format: Kindle
The they/them pronouns made for difficult reading at times but the strength of the family a friendship dynamics more than made up for that. An adult reader may see some of the ‘surprises’ coming but typical middle grade readers probably wouldn’t be able to read between the lines well enough to spoil the surprise twists.

A book with so much heart
Format: Kindle
An absolutely delightful story with the perfect amount of spookiness. Light-hearted but also deep in its exploration of the ways we push down our own souls because of what we think others need.
