The case surrounding Jodi Arias' first-degree murder of her ex-boyfriend Travis Alexander in 2008 has captivated the nation—and it isn't over yet. As Arias sits in an Arizona jail cell awaiting the selection of another jury for a new sentencing phase, what's next for the embattled defendant?

During the intial trial, defense attorneys argued that the 32-year-old California native killed Alexander in self-defense because he was physically and emotionally abusive and sexually exploited her, reports the Associated Press. However, the jury sided with prosecutors who claimed that Arias' jealousy drove her to deviously plot and carry out a cruel revenge murder after he began seeing other women following the couple's breakup.

Arias was convicted of first-degree murder on May 8 in the ghastly death of Alexander in his suburban Phoenix home. The original jury only took three hours of deliberation to decide Arias had killed Alexander in an "especially cruel, heinous, or depraved" manner that would warrant the death penalty. Medical examiners found that Arias stabbed Alexander 27 times, primarily in the back, torso and heart. She also slit Alexander's throat from ear to ear, nearly decapitating him, and shot him in the face, before she dragged his bloodied corpse to the shower. In total, the gruesome killing was done in a little less than two minutes.

However, the same jury failed to reach an unanimous decision on her sentence. As a result, she will face another trial to determine whether she will be sentence with capital punishment or life in prison.

A new hearing will take place on Aug. 26.

In the meantime,
HLN TV host Jane Velez-Mitchell's new book "Exposed" details Arias' long history of stalking behavior and her obession with Alexander. According to Velez-Mitchell, Arias previously dyed her hair blond and got breast implants to look more like one boyfriend's ex-wife.

The book goes on to say that Arias was clingy and jealous from the start of her relationship with Alexander, a motivational speaker and practicing Mormon, in 2006. She was also determined to marry Alexander even when the relationship seemed purely sexual, Velez-Mitchell writes.

The book is scheduled for release on Aug. 20.
