Train of Thought is a book of poetry that started life as a bit of fun as the author filled some spare time at work. Realizing his potential he took to writing poems on his train journey to work. As described in the opening poem "Train of Thought" he uses his forty five minute train journey into work to put down his thoughts into rhyming verse creating pleasing stories that are guaranteed to raise a smile. By his own admission some were more difficult to write as he analytically describes the changes he noted following his son’s two tours in Afghanistan as a serving member of the 3rd Battalion the Parachute regiment. His poems explore his inner thoughts focusing on his work, family and pets. Others are descriptive renditions of scenes put into words while some are drawn from the deepest annals of his mind that take you on a wondrous journey of thought. All his work will at least make you think, smile, laugh and maybe draw a tear.The author is Mark Williams a forty seven year old Civil Engineer. Born in Liverpool in 1965 his childhood was a happy one tainted by the misery of his parent’s broken marriage and frequent fighting. His attempt to capture this time in his poem "Scream" is possibly his most moving and compelling piece of work to date. This book is dedicated to Lewis Hendry, good friend and 3rd Battalion the Parachute regiment colleague of the author’s son. Lewis was killed in action on a 2010/11 tour in Afghanistan two days before his 21st birthday.
