"The book is a significant contribution to understanding the important yet shifting patterns of relationship between the monarchy and military in Thailand. It is widely known that the monarchy-military union has played crucial roles in politics throughout modern Thai history. This book: A Soldier King: Monarchy and Military in the Thailand of Rama X offers a comprehensive account and sound analysis about the newly formed monarchy-military network, demonstrating clearly how the new king tightens his grip since late 2016 as well as his different style from his late father King Bhumibol." -- Charnvit Kasetsiri, Thammasat University, Bangkok
