Holly Jackson: Not quite dead yet, Michael Joseph, July 2025, c format paperback, 9780241753699, I read a proof, thank you Michael Joseph

"Not quite dead yet" is a very pacy, unusual thriller. We know from the start there will be no happy end as Jet Mason will be dead within a week. Someone tried to kill her but left her with an inoperable head injury that will kill her within 7 days. Jet is determined to find out who wants her dead and receives help from her best friend from childhood, Billy,  whose father is part of the investigative policeforce dealing with the crime.  

I know this book will find many happy readers, Holly Jackson is a very successful YA author with a BBC and Netflix series and a huge flollowing. 

And this is exactly my problem with the book, the protagonist Jet does not strike me as a grown 27 year old woman but comes across  very YA-ish setting the tone of the thriller. Perhaps this is what the author intended but it did not appeal to me.  The crime plot is sound and unusual, however 75 % in I kind of knew who the villain was as the options very limited.
