Book Review - Right out of the gate, “Noble Ultimatum” by Author L.T. Ryan will grab you and keep the reader fully immersed. The story is another action-packed thriller that was quick, engaging and had lots of twists and turns. Following the assassination of a regular CIA character, main character Jack Noble disappears because the CIA wants him for the murder of that character. They don't want to bring Noble in to find out what happen, they – the CIA are in full attack mode, and they just want him dead! Outmanned and outgunned, Jack Noble, wanting to clear his name, faces the toughest challenge of his career, running from the CIA! And to make things worse, another shadowy agency is after him and his partner Bear Logan for no unknown reason. Ryan tells an explosive tale of hunt and chase interwoven with lots of blood and dead bodies during the adventure. Ryan is known for writing some extremely aggressive action scenes and in this story, there is plenty. He also surprised me with incorporating a little romance in this story as well. Always against the wall, Jack Noble and Bear Logan always seem to find their way out of trouble in this series. Noble Ultimatum, book 13 of the series, is no different. Very exhilarating storyline but the ending concluded with some loose ends. I’m not a fan of cliffhanger endings but I will most likely read the next Jack Noble book just because I enjoy this series, very solid and robustly entertaining.
