A Little Familiar by R. Cooper - I just read this one this week and loved it. It was wonderfully seasonal and had witches and familiars and I adored Bartleby.
The Tutor by Bonnie Dee - Another that I read and enjoyed recently. It's a historical with a Gothic feel and ghosts and a creepy old house.
Once Upon a Haunted Moor by Harper Fox - Harper Fox's writing is always lovely and really evokes the eerie moor. It's also the beginning of a series about these two wonderful characters. I love the every book in it and am hoping for another.
Fish and Ghosts by Rhys Ford - I always enjoy Rhys Ford's books, and this one involves a hotel for ghosts, including one that is pretty scary. The sequel is Duck Duck Ghost and it's great too.
Spirit by John Inman - Another with a ghost but with lots of humor thrown in too.
Kick at the Darkness by Keira Andrews - Zombies and werewolves, and this book did scare me a bit - I should not read zombie books, and I will remember this in the future. But the romance is wonderful, and I loved it anyway.
Iron & Velvet by Alexis Hall - I just read this and I'm wondering why it took me so long. A paranormal investigator, vampires, werewolves, demons, witches, some creepy monsters, and it was thoroughly entertaining.
The Darkest London series by Kristen Callihan - Magic, werewolves and other supernatural creatures in a Victorian setting. Loved the characters and the romances and the writing.
The Whyborne & Griffin series by Jordan L Hawk - Really any of her books fit and I'll reread them any time of year. They all have wonderful characters fighting creepy monsters.
The Charm of Magpies series by KJ Charles - This is another of my favorite series that I'll reread at any time. Another historical setting with characters I love. The second book has seriously creepy giant rats.
A Discovery of Witches by Deborah Harkness - Witches, vampires, demons, and it all starts with a book in the Oxford library.
That turned into a longer list than I planned! What do you like to read at Halloween?
