This is the second book in a series, and I think it's best to read these books in order. 
 Isaac and David have fled their Amish community in Zebulon, Minnesota, and are living with Isaac's brother Aaron. Aaron had left Amish life ten years ago, and has completely adapted to the 'English' life. He got a college degree and is now a teacher, and married to a Filipino woman who is a physician. They live in San Francisco, and are fully willing to support a David and Isaac until they can support themselves. They also fully accept Isaac and David being gay. 
 This book is told from David's POV, and David is truly struggling. By leaving he abandoned his mother and four younger sisters. He was the only man of the family and he fears that they are struggling. He is too scared to write and find out however. Adjusting to English life is difficult in some ways, and not in others... 
 Isaac smiled sadly. "It's amazing, isn't it? How quickly we get used to breaking the Ordnung. Practically everything we do here is against the rules. But once you start, it's easy." 
 "Easy not to think about it, at least." For when he thought about it, David remembered how hard things were in Zebulon. His chest tightened as he imagined how Mother and the girls would be struggling without him. Who would break the ice in the well, or chop the wood for the stove? Or-- 
 As the cable car dropped off its passengers and did a loop around the turntable to face the way it had come, David shook his head as if he could shake free his thoughts. He could never go back. Only forward with Isaac. 
 Being in San Francisco and seeing openly gay people is a huge culture shock. Isaac and David have believed their love is a sin, but witnessing other men embracing and even kissing helps them to better accept each other. 
 "I want to worship you," he whispered. Isaac was beautiful and good, and David wanted him to know it. 
 Groaning, Isaac dragged David's head down for a hard kiss as he spread his legs and wrapped them around David's hips. Isaac gasped, "It doesn't feel wrong. Does it?" 
 David could only shake his head, desperate for them to be naked so he could experience the heat and sweat of Isaac's body against him. Since that first night among the trees with loyal Kaffi standing guard, touching Isaac--loving Isaac--had only ever felt right despite everything. 
 Not only because of how good it made David's body feel, but in the way it reached into his soul through every pore. In every shared moan and smile, in every tremble of limbs and press of lips, he was whole. 
 Their love is strong, but distance does begin to grow. Isaac decides to go to school, and David nervous to begin a carpentry business on his own. Everything this place is foreign, and David is embarrassed about how little he knows and understands. 
 "I'm so glad you're here. If you'd stayed, I don't know what I'd do. I'd miss you so much I wouldn't be able to stand it." 
 "I'll never leave you, Eechel. I'm right here. Go back to sleep." He kissed Isaac's head. 
 David stared at the faint pattern of the street lamps through the blinds, shadows and light spreading over the walls and ceiling. His earlier resolve grew stronger with each little shuddering breath Isaac took. 
 No more procrastination and naps. He'd get his business up and running so he could take proper care of Isaac. He would keep him safe and happy. He wouldn't disappoint him. As Isaac burrowed close, David petted him and murmured a lullaby he hadn't heard in years." 
 David's struggle is intense and silent. He's afraid to confide in anyone, to reveal his fears which leads to panic attacks, and further separation from Isaac. Isaac wants David to meet his friends from school, but David is ashamed that he will appear stupid to them, and continually puts it off. Plus, other men are showing too keen an interest in David, and Isaac suspects David wants someone else. There are lots of hurt feelings, lots of empty liquor bottles and lots of tears, but things end on a strained (but POSITIVE!!!!) note. 
 I can't believe I love gay Amish romance, but I totally do. This series has me hooked. The feelings are so raw, and there's a good amount of sexytimes. I am anxious to see how David and Isaac move forward, together, in the next book.
