A book that makes you think!
Format: Paperback
This was a super good read, very imaginative. It dealt with identity, belonging, insecurities, family matters. The way it was written was unlike any book I’ve read this year.

The Possibilities
Format: Kindle
Despite its potential, this book ultimately failed to resonate with me. I found myself repeatedly compelled to put it down, as the focus on the empowerment aspect was overshadowed by the narrative’s preoccupation with re-triggering ourselves through the perpetuation of a harmful lie. This lie, which has tragically cost many Black men their lives and livelihoods, diverted our attention from the more profound themes of rebuilding culture, redefining ourselves, and creating a new world. Instead of exploring the possibility of a beautiful utopia, we were subjected to a process of de-centering ourselves and centering them, their likeness, and the relentless pursuit of proving our worth. While there were indeed wise words that moved me, I was left questioning the purpose of dedicating so much time to those who did not share our sentiments. Who are these individuals who required our convincing, and who are we who felt compelled to do so? I found Sydney, her family, and the inhabitants of Orange Beach to be unlikable characters. I fear that the plot was compromised when the focus shifted to inclusion.

Wow! Loved it!
Format: Paperback
Wow, I don't even know what to say about this book, but well done. I was a little bit mystified in the beginning. Our FMC and MMC definitely had me feeling a specific sort of way. A father, who was released from prison after "The Event" where all the white people in the Nation killed themselves, struggles with his identity. His daughter, Sidney, a biracial young adult who was raised by her white family, struggles with the fact that things she was taught were not necessarily true, and finds it hard to connect to her blackness. This is a tumultuous story of a beautifully written adaptation to an entirely new way of life. I didn't necessarily agree with certain ideations of the author, who in his book, claimed that there was a lost feeling after "The Event," but that's just personal experience, and I think that many black people would adapt. This book brings up so many feelings. How would I feel if "The Event" happened? Now that the "system" is dismantled? This book brings up dialogue and conversation. Amazingly well done. I'm still pondering. I know that this will be something I think about often. Wow. Very seldom do I tear up at books, but the representation of black joy in this story genuinely made my heart feel full. The love that when black people come together with nothing but amazing energy, was described so adequately in this book. I could feel it myself. And to that, I have to applaud Cebo Campbell.
