by Karin Slaughter and Lee Child

#popsugarreadingchallenge prompt 31: gold in the title

This is a short story with a running character from each author. As such it probably means more to fans of both series. I no that person but I still really quite enjoyed it.
It felt like each author wrote alternating chapters because the writing style varied greatly. As a reader of some Slaughter work I am pretty sure I recognized her chapters and I am not sure I like the choppiness of Child.
However, the book did its job and I will read more books with the main characters in them. As a hook to get readers introduced to new series, this little book is successful.
