Bonea is first mentioned in Ghost Story, and first appears in Skin Game.


In itself, she looks like a small cloud of greenish sparks inhabiting a wooden skull Dresden originally crafted for Bob.[1]

In Dresden's mental world, the spirit looks like a little girl about twelve years old, around puberty. Her appearance is based on Dresden's own as well as on that of many women important to him: her hair is dark like Dresden's, Lash's blue-green eyes, Karrin Murphy's square, balanced chin, the Archive's rounded cheeks, Susan Rodriguez's jawline, Elaine Mallory's nose, and Kim Delaney's hair.[2]


Bonea is a spirit of intellect, born of Dresden and Lash, who sacrificed herself for him in White Night. A part of her remained in Dresden's mind, letting him play the guitar, and hear echoes of her in his head. The "parasite" formed from these remains and parts of Dresden's own psyche.(reference needed)

In the seriesEdit

Ghost StoryEdit

In Ghost Story, Demonreach mentions her as keeping Dresden alive and metabolically active.[3]

Skin GameEdit

In Skin Game, Mab informs Harry Dresden that he only has three days before she kills him and that he will have to do her bidding if he wants to be cured.[4] The threat stems from the parasite's growth, which at first causes increasingly bad headaches but ultimately threatens to rip Dresden's head open, as the spirit needs to escape it to keep growing. In return for his service, Mab provides Dresden with a magical earring that freezes her, preventing her from growing and disrupting his work. As the earring's magic expires, Dresden collapses from headache, but is saved by the timely arrival of Molly Carpenter, who delivers the spirit and transfers it in the wooden skull Dresden made for Bob.[5]

Peace TalksEdit

In Peace Talks, she helps her sister preparing pancakes for breakfast, informing Harry Dresden and Thomas Raith she has two hundred and twentyseven recipes for them.[6]

Word of JimEdit

In a Reddit AMA, Jim Butcher officially confirmed the name, and that she is nicknamed Bonnie, an old Scottish name meaning "beautiful" and a wordplay on "bones".[7]
