This excellent thrilling adventure is a combination of sailing, marine archaeology and the dark secrets of the Order of the Knight's of Malta. I love these types of books that enable me to have an exciting adventure from the safety of my armchair! Especially appealing is that I have always wanted to travel trees to Malta. This is a wonderful, slow burn mystery and I definitely recommend it.

Knight's cross by Christine King is a mystery and thriller and general fiction (adult) read.
Shipwreck hunters Maggie Riley and Cole Thatcher are no strangers to the mysteries hidden beneath the seas. They’ve uncovered artifacts with secrets that powerful interests would do anything to control—and they’re about to do it again.
As the newly engaged couple prepares to set sail, Cole suspects they are being followed. While he tries to unravel a coded message that hints at a treasure jealously guarded by an ancient society, a bomb is discovered on the couple’s yacht. Now it appears that Cole’s belief isn’t mere paranoia—and that the cipher holds information others will kill for.
This was a really good read with good characters. I loved how Cole and Maggie were together at helping people. 5*. I voluntarily reviewed an advanced copy of this book from netgalley.
