I found this quite hard to follow and I just couldn’t get into it

Loved the premise, but this was a very convoluted story with a wildly confusing ending.

My Dear Sister by Fiona J. Pinkerton
🌟🌟🌟🌟
This is an exciting and suspenseful twisty thriller!
The story is entertaining and I enjoyed some of the shockers! However, I do think a lot of information occurred in such a short story. If it had been longer and a bit more in depth, it would have been a little easier to follow.
But I enjoyed the premise and overall storyline! It kept me on my toes!!

So this short thriller is the author’s debut, I think? - I personally found it really intriguing! At first I was a little confused with how it jumped right in, but it didn’t take long for me to understand and I wound up really liking how each chapter was a letter.

Less than 50 pgs, this is a fast read and showcases the darker side of a sibling. Three sisters torn apart by a tragic hit and run. One sent to prison, one sent away to disappear and one who eventually tries to piece everything back together. The story unfolds as the two older sisters write back and forth, one begging the other to stop digging the past up for her own safety.

I found this to be a page turner and would definitely read more stories by this author!

“My Dear Sister” by Fiona J. Pinkerton is a dark, twisty short story centered on three sisters. The tension builds steadily, the atmosphere is heavy with unease, and the ending delivers a chilling punch. Pinkerton’s writing is sharp and immersive, making this a powerful, haunting read that proves how much impact a short story can have.

I was really liking this short story when it was just the two sisters at the beginning. Once the third was included I was so confused all the way till the end.

[Manali · Rating 4 out of 5]

This started out so well and was top-notch thrilling till about the 80% mark on my kindle reader but then it became very confusing, very fast, and ultimately also very disappointing from thereon.

I listened to this one! Interesting twists. Short and sweet - to the point.

I liked this short story until the end which I didn't understand at all. Very disappointing.

3 sisters and 1 huge lie. What happens when 1 sister can not give up looking for the truth? The second sister begs her to stop? And the third sister who was believed to be “gone” was really close by this whole time. Will the true story come out and unravel all of the lies, or will the lies continue to hold true for these sisters
