This book is standalone, another book by this author is ‘Four Good Liars’.

Here is a summary of this book;
Science-obsessed Grace’s fresh start with her dad in Devon is derailed when the smart speaker in their new house comes alive at midnight and says: “I’m going to murder you.”
When Grace begins to investigate, she realises that the four previous owners of the device met four mysterious deaths that were all “accidents“. Only Grace knows that one of those deaths was actually a murder. Now she must identify both the killer and the victim, using the methodology of a chemistry experiment, before she ends up dead herself.

I really enjoyed this book, I liked how instead of just looking for the murderer, the main character also needed to investigate to discover the victim using ‘methodology of a chemistry experiment’. I would recommend this to anyone who likes mysteries and science.
