Natalie Beck is a prisoner in her own apartment. A prisoner of fear. As a successful writer, her homebound state fuels her career, but she longs to return to the days when she traveled through the city freely and without fear. She interacts with very few people and avoids any and all contact with new people and situations. Just as it appears she is making strides towards conquering her fears, she receives a set back that negates all the effort she has expended over three years. 
 Jake Tanner is determined to find out who is sending Natalie disturbing messages. The notes have finally caught the attention of her cousin, who hired Jake to investigate the notes in hopes of relieving some of Natalie's fears. He doesn't intend to develop feelings for his client, but as they begin to converse, by text and phone with no face to face, he finds something in Natalie he didn't know he was looking for: acceptance. 
 I love Jake. Everything about him is perfect for balancing out the fears Natalie feels. From his quick understanding of how to put her at ease enough for him to install security measures, to pushing her (gently) to accept his presence in her life as a new person. He has his own challenges, both as the owner of a security company and as a combat injured amputee, but he also uses his experience to be a safe place for Natalie to vent her fears and worries without feeling judgement or pressure. 
 I was sympathetic to Natalie's agoraphobia, though I've never faced fears that debilitating in my life. Her fears and anxiety were written in such a way that at times it overwhelms her character, much the way it would overwhelm her life. Knowing she was so focused on only her fears and her writing, there wasn't a lot to her character as far as depth, but it was easy to fall in love with her as she struggled to overcome the crippling symptoms she experienced. 
 I also love the way Natalie helps Jake face things he didn't even know he hadn't accepted. As an individual she pushes herself. She isn't about wallowing in pity or looking for attention. She just wants to be normal and turns to the few people around her to help -- her cousin, her therapist, and her editor. 
 I can't say I was surprised at who was behind the threats, but it was still a shock to see it in front of me, almost like I continued reading hoping I was incorrect. The ending happened rather abruptly, but it was also written in such a way that the speed of the resolution worked for all characters. 
 But I loved the way this story developed. Though it wasn't a speedy timeline, it was a fast read. The only moments that hit me as awkward or not quite to my taste were a couple of the intimate scenes, which understandable are rather personal. One scene in particular just felt like it was ill timed based on other events that had just taken place. 
 Overall I really enjoyed this story. Ian and Kaga are present as Jake's friends. Readers also get to see quite a bit from Jake's sister Sabrina, and if the bits and pieces can be fit together, there is quite an attraction between Sabrina and Kaga, though Jake disapproves. Their story certainly seems to be filled with conflict and building tension.
