Sulu and Chekov are accused of treason and it's up to Uhura and Kirk (and to a lesser extent, Scotty, McCoy, Rand and Chapel—Spock remains a no-show) to help them out. This book was fine; infinitely better than "A Flag Full of Stars," the previous 'Lost Years' novel, but still nothing all that special. On the upside, it puts its focus squarely on Uhura, Sulu and Chekov who are often relegated to background roles even in the novels. On a technical level, this book is well written. Its characterization is spot-on, the action and dialogue are all solid, it's just that the plot and the mystery driving it don't end up being super compelling.
