Lucy, who joined MIC in 2012, wrote the book to give girls more advice on relationships and the dating scene.
Tweeting to fans last night (15 April), Lucy said: "If I could have given my book to myself when I was 15 it would have saved me hell of a lot of pain."
In The Dating Game, Lucy will offer a modern girl's guide through the perilous world of first dates, falling in love, break-ups and the emotional minefield of exes.
Lucy will also open her heart and discuss her own personal dating experiences of serial-cheaters, public betrayals and sex scandals.
Since joining MIC, viewers have witnessed Lucy's failed romances with her co-stars, including several dates with Andy Jordan and Alex Mytton.
Lucy has also dated Spencer Matthews and recently embarked on a very brief romance with Jamie Laing.
The Dating Game, published by Quadrille Publishing Ltd, hits the shelves on 22 May.
Made In Chelsea continues every Monday at 10pm on E4.
