• An A+ option B. Sheryl Sandberg's new book, Option B: Facing Adversity, Building Resilience, and Finding Joy, went on sale—and shot to the top of the Amazon bestseller list—yesterday. The launch and surrounding events prompted a number of interesting pieces. Here's a sampling of what caught my eye:

While the book centers on Sandberg's story of facing the unexpected death of her husband, Backchannel's Jessi Hempel's writes that, "Even more than Option B is a self-help tome, it's a management book. Sandberg shows how a boss can lift a whole organization by admitting she (or he) needs help." It has the potential to revolutionize the way we work, dismantling the wall many still try to erect between our "work self" and our "real self," and, as Hempel puts it, revealing that "your vulnerabilities, when shared, are your most effective tools for working with other people."

Fortune's Valentina Zarya focuses on a different aspect of the book: Its insight into how we can best support the people in our lives who are confronted by grief (in other words, everyone, at one time or anther). Sandberg provides simple, logical guidelines that can help stop us from saying and doing the wrong thing—or worse yet, nothing.

Appearing at the 92nd Street Y this weekend, where Sandberg and co-author Adam Grant were interviewed by Katie Couric, the Facebook COO talked about the way in which Couric—another very public widow, whose first husband died 1998—helped her through her grief. "You jumped in and kept telling me it would get better," she told the Yahoo anchor. "And you were more credible because you had been through it."
