In Pocketful of Posies, author Jo Treggiari gives more back-story on Del, Aidan and Sammy. It covers the period of time when the first plague cases begin to appear. The first three chapters are available on Jo's website.
Writer, reader, and bookseller. My newest book, a YA psych thriller, is Blood Will Out (Penguin, 2018). My next book, another YA thriller, The Grey Sisters, will be published in 2019. I'm always working on the next thing.
I found this description on Jo Treggiari's website: "I began writing a companion book to Ashes, Ashes to give a little more back-story on Del, Aidan and Sammy. It covers the period of time when the first plague cases begin to appear." You can read the first 3 chapters on her website under Ashes, Ashes :)
