There is a new biography of General Custer that I highly recommend to you, especially if you are interested in him.

“Custer’s Trials: A Life on the Frontier of a New America” by T.J. Stiles

Its focus is on his entire life in the context of the times he lived in. It is divided into two parts: Birth through the end of the Civil War and End of the CW through his death.
