This book for me originally was a cover buy. I saw it and without knowing anything about it, bought it...and I am so glad I did. The Brilliant Death takes gender fluid to a new level where Teo, a mafia don’s daughter and Cielo are both Strega and able to gender change, actually physically change between male and female, with use of the magic inside of them. This book is imaginative and original, creating new worlds of magic and characters cruel and tender and loving and interesting all in one. She has a big hearted brother Luca whom she wishes to protect from her beyond evil older brother, who tortures his siblings in twisted ways. This book moves in so many interesting directions with clear world building; I will eagerly eat up book two as soon as it is available to me!
