English 4/3rd Hour discussion

At a bar, Cantwell meets up with a love interest by the name of Renata. She is very young at 19 and he is middle aged at around 50. Renata did mention how she fears him dying before her in combat or other causes but she has strong feelings for him. The reader also finds out that the main character, Cantwell has made few big mistakes in his life. He did not go into detail but his biggest regrets are losing three of his battalions and has lost three women, the causes were not revealed. A lot is being introduced in the book but is not being explained which leads me to want to read more so that I can learn details
