Good Girl, Bad Blood is a YA mystery/thriller, the second in a series. I bought my copy new.
Review:
After the events of the first book, Pip is determined to no longer do detective work. She's still working on her true-crime podcast, but now it's focused on the murder trial related to the case she'd previously investigated. There won't be any new investigations.
That lasts until Connor, a friend of hers, asks for her help after his older brother Jamie goes missing. The cops aren't taking his disappearance seriously because he's disappeared a couple times before and come back, but Connor and his mother are convinced that this time is different.
Pip agrees to look into his disappearance and ask for leads from her podcast listeners. But as she starts to get as obsessed with this case as her previous one, she and those around her wonder whether she can handle this kind of strain again. Surely it's worth it if she can find Jamie, right?
