First Lines Friday

First Lines Fridays is a weekly feature for book lovers hosted by Wandering Words. What if instead of judging a book by its cover, its author or its prestige, we judged it by its opening lines?

• Pick a book off your shelf (it could be your current read or on your TBR) and open to the first page
• Copy the first few lines, but don’t give anything else about the book away just yet – you need to hook the reader first
• Finally… reveal the book!

Kelda’s little sister seemed like a perfectly normal baby until her seventh day, when it was time to throw her in the river. They they found out she couldn’t breathe underwater.

Any ideas?
