Let me begin by stating that as a southerner, I grew up being taught to utterly despise Sherman, specifically regarding the misery and huge swath of destruction for which he was directly responsible throughout the south during the ACW. He burned many of my direct ancestors out of house and home during his Meridian Campaign. My 3rd Great Grandfather, who served with the 2nd Alabama Cavalry (1862-1865), made his military career fighting specifically against Sherman for the majority of the ACW. He fought him from 1863-1865 in northern Mississippi, west Tennessee, northern Alabama, he opposed Sherman on his march from Memphis to Chattanooga, during the Meridian Campaign, the Atlanta Campaign, in northern Georgia and Alabama after the fall of Atlanta up until Hood went into Tennessee, he was fighting on Sherman`s right flank and harassing his rear during the March to the Sea from Atlanta to Savannah, he fought and participated in the siege of Savannah and opposed Sherman after the fall of Savannah through South Carolina and North Carolina, until the close of the ACW.
In stating all of the above, as a proud American and a former U.S. Army Paratrooper, whose 9th Great Grandfather first came to this land in December 1607 (Jamestown Colony), and whose direct ancestors on both paternal and maternal lineages fought to found this country during the Revolutionary War, I am impressed with Sherman regarding his military brilliance and battlefield strategy. In my opinion Sherman won the war, more-so than any other field commander of the Federal Army. Without Sherman, Grant would not have had the success which was credited to him. In my opinion 1864 was the turning point of the war, and what Sherman accomplished in the Western Theatre had much to do with that.

@Nathan Stuart stated in his response above, I thought '
Sherman's March' (335 pages) by Burke Davis, was an excellent book regarding Sherman. That is the book that I would recommend. It is an older book (1980), one that I have had in my collection for several decades, but it is well written and very informative. I believe that you would get a lot from it.
