Is Jinger Duggar throwing shade? The 24-year-old took to Instagram over the weekend to share a book recommendation, and some fans think she’s side-eyeing her sisters! “Hey single ladies,” she wrote on Instagram. “You may be interested in reading a book I am going through with some of the other women from my church—She’s Got the Wrong Guy: Why Smart Women Settle by @deepakreju. Jeremy and I read it together and really enjoyed it ? || Search for it on Amazon!”

According to Amazon, the book is about how “the nicest women pick guys who let them down.” The author, Deepak Reju, shares his perspective on “how to assess a relationship’s strengths from the beginning, how to identify possible pitfalls, and how to have the courage to not just settle, but to wait for a relationship that will be a blessing to both of you.” Counting On fans immediately started pointing fingers at Jill Duggar and her disgraced husband, Derick Dillard.

Derick has been in hot water for a while regarding the transphobic tweets he wrote about fellow TLC star Jazz Jennings, and most recently, for calling Nate & Jeremiah by Design stars Nate Berkus and his husband, Jeremiah Brent, “a travesty of family.” Therefore, some fans think Jinger is subtly sending a message to Jill about her controversial man. “What Derick did was unprovoked and hateful,” one user wrote on Jinger’s post. “We are all entitled to our individual beliefs, but we must do it in a respectful and loving way. Derick did neither.”

On the other hand, a couple of users think Jinger is warning her older sister, Jana Duggar — who is unmarried — to never settle. “She probably meant Jana the older sister that is single,” one user wrote. It’s unclear if Jinger is trying to warn her sisters, or if she’s simply just looking to start a book club with fans. Either way, we’re excited to check out her suggestion!
