Not from the Confederate side and unfortunately only covers the opening of the campaign up to May 1862 but still none the less probably the best balanced account IMO is Russel Beatie's Army of the Potomac volume 3. Although he sustained at times rather savage criticism (particularly for the first volume) he tends to cover the machinations of the time from often a unique perspective. I found that he had responded to the criticism of the first volume by the time the third volume was published and is thought provoking in what he has to say. He was due to complete his work covering the whole of the Peninsula campaign in the next volume but sadly he passed away in 2013. If I have not encouraged you read volume 3 then perhaps this quote from a review of volume 3 perfectly summarises the reasons as to perhaps giving it a try:
In meticulous fashion, Beatie examines many heretofore unknown, ignored, or misunderstood facts and events and uses them to evaluate the campaign in the most balanced historical context to date. Every aspect of these critically important weeks is examined, from how McClellan's Urbanna plan unraveled and led to the birth of the expedition that debarked at Fort Monroe in March 1862, to the aftermath of Williamsburg. There were many reasons why the march to Richmond did not move as expeditiously as many hoped it would, though until now, few of these reasons have been satisfactorily (or even fairly) explored.
