This book about Italian Frogmen states it is a work of fiction based on real events, but I didn’t get far enough to know or confirm its accuracy. I did not finish it, actually stopping reading a little way in for two good reasons.

The first is formatting: there are no new lines for speech, scene breaks, or paragraph breaks, making it hard to tell who is talking, and presenting the reader with a wall of text.

The other is the English. Two notable examples marked the page where I quit.

“None ships were in sight.”

And

“Within minutes was they eight men.”

I could give further examples, but almost every sentence on the page is like this. Read the Look Inside before you buy.
