Marital Advice to my Grandson, Joel: How to be a husband your wife won't throw out of the window in the middle of the night. by Peter Davidson

Summary by Goodreads:
When my grandson, Joel, got engaged, I decided to jot down a few words of marital wisdom for him, based on my vast experience as a husband. Then I thought, why share this wisdom with only one person when I can share it with the whole world. So, I started a blog, listing new marital advice every week. As the popularity of the blog grew, people suggested that the material should be turned into a book and, well, here it is!
Sure, much of the advice is off-the-wall and wacky, but it’s also an upbeat, humorous look at married life that any engaged or married person can relate to and will find insightful and fun to read. Even unmarried people can enjoy the book and, who knows, it might convince some of you to take the plunge, or perhaps confirm your belief that being single is a blessing.
Advice to Joel, and to any man, includes: make sure that you buy a roll of electrical tape before you volunteer to do the vacuuming–and why, how to deal with your wife’s steely-eyed, clinched-jaw scowl, known as “The Look,” how to answer your wife’s questions such as, “Does this dress make my ass look big?,” the warning that your mouth will get you into a whole lot more trouble than your Willy ever will, and how to create the world’s most powerful anniversary card for your wife.
Virtually all of the material in the book is presented in the form of upbeat stories, scenarios, and examples. This is not the type of advice that you’ll find in a textbook on marriage or in a book on marital relations written by some psychiatrist. This is the real stuff for real people.

Shy Girls Write It Better by May Sage

Summary by Goodreads:
Cassie Franklin trips over nothing on perfectly flat surfaces every day, and she cannot seem to be able to simultaneously speak and look into her audience's eyes.

Cassandra Frank is the ultimate tease; her words have aroused, intrigued and captured the heart of thousands...
And somehow, they are the same person.

Hiding the fact that she writes erotica isn't much of a challenge - no one would ever think that a plain, boring little accountant like Cassie could so much as read anything so scandalous...
But one day, she makes a huge mistake.

Carter Harris employs so many people he can't exactly recall all their names, but strangely, he knows her. She isn't an executive, she isn't sexy, or otherwise noticeable, but the girl is cute - in a helpless, unique sort of way.
He can't pretend to say she ever crosses his mind, though... Until the day he finds the manuscript she worked on during her lunch hour.
