Teaser Tuesday with Heart Sick

Teaser Tuesdays is a weekly bookish meme, hosted by MizB of Should Be Reading. Anyone can play along! Just do the following:

• Grab your current read
• Open to a random page
• Share two (2) “teaser” sentences from somewhere on that page
• BE CAREFUL NOT TO INCLUDE SPOILERS! (make sure that what you share doesn’t give too much away! You don’t want to ruin the book for others!)
• Share the title & author, too, so that other TT participants can add the book to their TBR Lists if they like your teasers!

I was in need of something out of my usual genre. And wow, did I find it. HEART SICK is the first book in Chelsea Cain's Archie Sheridan and Gretchen Lowell series. A crime thriller with a female serial killer, and Gretchen is as frightening as they come. The book hooked me immediately with the first short chapter. I was blown away.

Here's your teaser:
Archie doesn't know for sure that it's her until that moment. There is a dull bloom of warmth in his spine, his vision blurs, and then he knows that Gretchen Lowell is the killer. (page 1)
