I Wish question - are there diverse characters in the I WISH series?

Yes. Several of the main characters across this series are diverse in race, ethnicity, or ability.

Eli Harper: Eli's mother is a black English professor at fictional Piedmont University. His father is a white civil engineer. Although Eli is biracial, it's incidental to the story. He's been raised in an affluent family. He's always lived in college towns. While his race is not ignored, it's not a plot point either.

Kimberley Rey: Kimberley's father is a Colombian-American, so she is half-Latina. Like Eli, her ethnicity is mentioned but not a plot point. (I chose Colombia because I was visiting there while I was writing the book, and the people and country are beautiful and friendly.)

Kimberley has permanent brain damage from the chemotherapy she received to treat childhood leukemia. Her resulting short-term memory loss is a disability, and that is a major subplot in Wishing for You. 

Grant and Camarin: Because they are not human, our Benevolent Supernatural Beings do not have an earthly race. Their descriptions are deliberately vague; I only mention their dark hair and unnaturally green eyes. The humans they serve (as well as readers) are welcome to imagine the appearance and ethnicity of the Beings however they wish.

Secondary characters: In I Wish, you meet Lacey's mother, Crystal, who struggles with depression. The family's financial problems make it difficult for Crystal to afford the mental health care (and medications) she needs. Readers will see glimpses of her in books 2 and 3. The impact of Crystal's battle with mental illness continues to affect Lacey and her brother. Just like in real life, Crystal has good days and bad.

In Wishing for You, readers will meet Scott and Paul Fuentes. They are Latino. Paul, an immigrant from El Salvador, is dating Kimberley's mother. Readers will see much more of his son Scott in book 3. Kimberley's dad has a partner, too. Nour is Lebanese-American. I chose Latino and Lebanese in honor of two of my friends.
