This volume of the Loeb Classical Library comprises two of the more important parallel lives by Plutarch. The present edition is the only option for the educated reader who wants to compare the English translation with its Greek original, either for quick reference or convenient extensive reading. The opinion expressed in another review on this site that the book is not worth reading because Plutarch is not faithful to the "facts" is just ridiculous. Plutarch is a classical author. Should the editor or translator write a new Greek text with the amendments that he personally thinks more adequate? To discuss the value of Plutarch's report is the task of classical scholars and ancient historians, not of online reviews.
You have ancient historians like Polybius, Thucydides, and Seutonius who tell the facts and do not change them. But with Plutarch, it's a different ballgame. Plutarch wants to make the good people look bad and the bad people look good. Try to avoid any book written by Plutarch for all the lives he has written about are sketchy. I was kind enough to give the book two stars so if you actually are resding this, here's my advise: if you have money to blow, get it and try and read it, but don't go out of your way.
