A lot of my friends, like me, love the Harry Potter books, after all this time. Here are three books similar to the series.
In Harvest Moon, by Tonya Coffey, strange things start happening to 17-year-old Jessa after her dad gives her a book. She discovers trolls are real and meets fairies.
14-year-old Joshua must battle monsters and deal with terrifying dreams in Onwaachige the Dreamer, by Jay Jordan Hawke.
Transcendent, edited by K. M. Szpara, features transgender characters in fantastical stories.
