Books about male lead being kidnapped

Hi! Ive gone there some posts on here asking for kidnapping related books and they all mostly seem to have female characters that are the main leads.

I would love a book about a male character being kidnapped or taken. It could be a character of any age, but i would prefer if it was not a romance. Something more of a mystery/thriller perhaps. Im really interested in reading about the captors as well and their reasonings and relationship with the new captive. They could be kidnapped for ransom or any other reason. It could be that they were caught as witness to a crime or that they have parents with influential or shady backgrounds or even be kidnapped as revenge for something they might’ve done. Literally anything related to kidnapping!

Any and all suggestions are welcome!
