From his first appearance on the page, Sully spent so much time boasting about how bodacious he
Also, he calls her "Chazzie-girl" and spends all his time ignoring her and belittling her in between his useless professions of love and her constant displays of competence. Well, relative competence. And I hadn't even gotten to his true awfulness, which the book club complained of. It wasn't so much that he kept secrets from her -- he was honest about the fact that he couldn't bear any questions and Chaz accepted that. But he would do things to her and conceal that, and then be all angsty when she got mad and make her comfort him for being so sad about being a tool. Yick!
I have enjoyed later Sinclair sci-fi romances, but in this one I felt Chaz ended up with a deeply untrustworthy man.
