Keepsake by Sarina Bowen is the third standalone novel in her True North series. While books one (Bittersweet) and two (Steadfast) don't HAVE to be read to enjoy this book, the timeline is continuous throughout the series. Also, the other books are equally as fabulous! 
 I really thought nothing could top the emotions that Jude and Sophie's book evoked but good Lord, this one was pretty darn close. Zach and Lark are so utterly different from each other. From their backgrounds to their upbringing and their views on life, except in all the ways that matter. They are such a great couple and their back and forth, their deliberation and Lark's healing process was so extremely well-written this book practically reads itself. I loved it! Enjoy!
