Leona Lewis has a voice like a monolith; a shiny, towering monument to perfect sound. But it can be difficult to connect with the woman who wields it, even with the help of pop-chart pros like Max Martin, Ryan Tedder, and Justin Timberlake.

When it works, however, as on the soaring ''Happy'' and feathery, synth-laden ''I Got You,'' all is (momentarily) redeemed. C+
