Lost Item No.: 1067200 - John F Kennedy International Airport, New York, US

Please help me find my book, it is very important to me. The book is about my grandfather who just passed away last week. I was on flight L026 from L'vov which landed at Gate 23 in JFK at 8:00PM last night (4/14/16). The book is Ukrainian, has a light blue cover and is called HЕСКОРЕНІ СИНИ І ДОЧКИ. I sat in seat 18J and the book was in my carryon stowed away at the top above row 17 and 18 (left side of the plane if facing back of plane). The book must have fallen out when I grabbed my bag. Please call me ASAP if found, I greatly appreciate your assistance.
