Both of those tales are worth reading, but the real highlight of this book is Wonder Woman #170, a story titled "She's a Wonder!" This standalone issue features an interview between Diana and Lois Lane as the two spend a day together and Lois learns a little about what it means to truly be Wonder Woman. This issue is widely regarded as one of the one of the best in Wonder Woman's long history, and it's well worth tracking it down even if you forego the rest of the book.
Wonder Woman was created by William Moulton Marston and Harry G. Peter, and has a lengthy publication history. This history has sometimes included a sidekick Wonder Girl and many villains. Since her debut she has become one of the most popular and recognizable DC Comics characters, along with Batman and Superman. She first appeared in All-Star Comics #8. (1941)
Wonder Woman was legally barred from appearing in the first few seasons of the Batman: The Brave and the Bold, but made a cameo from behind in the episode "Sidekicks Assemble!" She later made a full appearance in the final season during the episode "Scorn of the Star Sapphire!," and played a main role in the episode "Triumvirate of Terror!" In the show, she was voiced by Vicki Lewis.
As the men helped the Amazons prepare for battle against the First Born's army, Diana received news that the First Born had been attacking other gods' realms. With Eros and Artemis, Wonder Woman ambushed the Minotaur at Demeter's home. Unfortunately, the First Born had already defeated Demeter, so Wonder Woman sent her companions to safety while she confronted him by herself.
The Lasso of Truth, or Lasso of Hestia, was forged by Hephaestus from the golden girdle of Gaea. The original form of the Lasso in the Golden Age was called the Magic Lasso of Aphrodite. It compels all beings who come into contact with it to tell the absolute truth and is virtually indestructible; in Identity Crisis, Green Arrow mistakenly describes it as "the only lie detector designed by Zeus." The only times it has been broken were when Wonder Woman herself refused to accept the truth revealed by the lasso, such as when she confronted Rama Khan of Jarhanpur, and by Bizarro in Matt Wagner's non-canonical Batman/Superman/Wonder Woman: Trinity. During the Golden Age, the original form of the Lasso had the power to force anyone caught to obey any command given them, even overriding the mind control of others; this was effective enough to defeat strong-willed beings like Captain Marvel. Diana wields the Lasso with great precision and accuracy and can use it as a whip or noose.
