At 780 pages, this isn't anything for the faint of heart or casual Teddy fan. But I am neither. And though it is long and detailed, it actually reads fairly quickly.
Richly detailed with plenty of humor thrown in, I am now a much bigger fan of Roosevelt. I knew the barest outlines of his life pre-president (this book is exclusively about his life before he became president in 1901), but I am struck again by his energy. In some ways, reading about Teddy is just exhausting, but in a good way.
At times, I would have liked a bit more context and also more about his family. Once he marries Edith, they kinda fade to the background.
Highly recommended--and a great choice for the long days of summer reading.
