Help! Need recommendations for buying a book for a Patricia Cornwell fan

.
Hi, I need suggestions for newer books an avid Patricia Cornwell fan might like. My Aunt is an amazing woman and has been my rock throughout my life. She has had a hard year and I want to go all out for Christmas for her this year. I have gotten her something useful, something sentimental and an experience. I wanted to included something new too. She has a special book shelf for all her Cornwell books and I would like to help find her a new author she will also enjoy . It would be preferable if the book has been released in the last four years but I’m open to any suggestions . Thank you to anyone who takes the time to respond.
