Grey Angel - First Sentence

The first sentence. An author's first and perhaps only chance to hook a reader. There are readers who stand in bookstore aisles and read only the first page, the first paragraph, the very first sentence before deciding whether or not to read on and perhaps purchase.

Here is the first line of my novel - Grey Angel.

The water was searing cold.

What is your initial reaction?

Yes, I have had feedback from several beta readers. And yes, some of them have asked if 'searing' doesn't imply hot not cold. Searing is defined as extremely hot or intense. I have considered using a less forceful word. But I am resisting the change because the juxtaposition does get nearly every reader thinking - just how cold is searing cold? So cold that it burns?

I won't make you wait for the whole first paragraph, here is the next line.

The water was searing cold. 

At 5 a.m. no one had drunk from the silver metal fountain for hours, 

the water had taken on a throat-numbing chill.
