Josiah Duggar's Ex Writing New Book About Love Following Split

Watch out, Duggars! Another scandal could soon hit the family.

As RadarOnline.com readers know, 19-year-old Josiah Duggar and his girlfriend, Marjorie Jackson, 17, split soon after news broke that his older brother Josh was accused of molesting at least two of his own sisters as a teen.

And now Marjorie, who was the family's close confidante for months during the courtship, has announced she's writing a new book for fellow teen girls— about love!

"Romantic sparks are fickle and unreliable—here one day, faded the next," she says in her blog entry about the upcoming project.

It seems quite possible that the budding author could draw upon her own failed relationship, and the chaos that ensued.

RadarOnline.com first revealed that the pair had parted ways after Josiah stopped posting photos of his new girlfriend to his Instagram page after months of loved-up snaps.

The couple was last pictured together in May— just days before a bombshell report painted father of four Josh, 27, as a sick child molester.

One day after RadarOnline.com's story, the Duggar family confirmed the breakup, noting that the romance was not in "the Lord's will."

Could Marjorie spill the Duggars' secrets? Sound off in the comments.
