A missing bride leads Nancy on a chase through Las Vegas in the twenty-fifth Nancy Drew Diaries, a fresh approach to a classic series.
Bess and George's cousin Veronica is getting married to extreme sports enthusiast Xavier Redd, and as a close friend of the family, Nancy has been invited to the wedding. Given the groom's big personality and love for the extreme, the wedding will take place in Vegas, and the couple plan to take advantage of local sporting opportunities in the week leading up to the big event.

Not everyone in the family approves of Veronica's fiancé, though, especially because of the risk-taking behavior Xavier has introduced her to. And when one of the couple's sporting stunts almost ends in a serious accident, it's not clear whether it's an unfortunate coincidence or whether someone really wants to stop the wedding from happening.

Still, the day of the wedding arrives. But when it comes time to exchange vows, the bride is nowhere to be seen. Is this just a case of cold feet? Or has one of the wedding guests created a cold-hearted plot? One thing's for sure—Nancy won't rest until she finds out.
