Book Beginnings on Friday (3)

Book Beginnings on Friday is a meme hosted by Becky at Page Turners. Anyone can participate; just share the opening sentence of your current read, making sure that you include the title and author so others know what you're reading. If you like, share with everyone why you do, or do not, like the sentence.

I'm currently reading Ice Station by Matthew Reilly, a thriller set in Antarctica. This is the opening sentence of the prologue:

It had been three hours now since they'd lost radio contact with the two divers.

I like this opening; we're taken right into the story and we realise immediately that something bad has happened. The question is what and to whom, and we have to keep reading to figure that out.
