A thrilling mystery that had me on the edge of my seat. The ‘LOST’ messages added a great layer of suspense. Highly recommend!

Enjoyed the spooky atmosphere. The plot had some holes, and the ending was a little weak. Still, entertaining enough for a quick read.

I liked the premise, but the execution was lacking. The characters felt a bit flat, and the pacing was uneven. Good but not great.
Ayush Gupta –
A solid mystery with plenty of twists and turns. The ‘LOST’ theme was well-executed, and the suspense kept me hooked. Great job!

I thought the book was alright. A few scary bits that were fun. However I had read better ones than this one.

The story had potential, but it felt underdeveloped. The ending was abrupt, and I was left with unanswered questions. Disappointed.

Another classic Hardy Boys adventure! This one has a darker tone, which I appreciated. A few plot contrivances, but still a good read.

I found this book to be okay. Nothing special, but not terrible either. A decent way to pass the time, but don’t expect too much.
Ayushman Singh –
A decent start to the trilogy. The mystery is intriguing, but the writing felt a bit rushed in places. Could have used more depth. However I liked how scary it was.
