This is an extremely interesting topic that is getting more attention because it's occurring more and more frequently... Books from popular authors -- published years ago -- are being plagiarized and resubmitted under new author names and covers on Amazon.
Here's an example of one book that's being accused of plagiarism -- it's currently ranked in the paid 2000s at $2.99 and it's currently being advertised through many of the popular discounted eblast services.
We're going to leave off author names and book titles because we don't want to add to this specific controversy -- but you can read the opening paragraphs and see for yourself the reason why readers are crying "plagiarism":
Opening Paragraph of alleged "copy cat" novel:
Draped in a white robe of satin and lace, Carina dived into the waiting limo, skidding over the expansive white leather seats and then sneaking a look out of the dark tinted windows before desperately asking the chauffeur to drive again.
Confused, the chauffeur began protesting. But Miss--"
"I said, drive now!" Carina demanded, struggling with the netting of the veil which clung to her face as she pulled it away.
Surprised by her ferociousness, Barnes hit the gas faster than he would have usually done, the tires of the car squealing against the tarmac as Carina's head snapped back due to the force. Carina sighed, her whole body being filled with relief as the car moved forward as it put more distance between her and the church. She could not believe that she had actually done it. She had done it! She had escaped and she was free!
Opening paragraph of the original work by a National bestselling author:
In a blur of white and satin, Louisa dove into the waiting limousine, slid across the expansive leather seats, then with a furtive look out the tinted windows, issued the desperate order again.
Befuddled, her driver started to protest. "But-"
"Now!" Lou demanded, frantically battling the clinging net of her veil from her face.
Startled by her vehemence, her drivers' usually light foot hit the accelerator hard. Tires squealed as her head snapped back from the unexpected jolt.
Lou blinked, then sighed with overwhelming relief as the big car swiftly lengthened the distance between herself and the church. Between expectation and duty and the marriage she'd never wanted.
She'd done it! She'd escaped!
