This is a book review of Gravitational Waves: How Einstein's Spacetime Ripples Reveal the Secrets of the Universe by Brian Clegg. A breezy, popular-science level introduction to gravitational waves and their detection by LIGO, it is well written, engaging, and somewhat different from books covering roughly the same territory. A welcome surprise is a description of LIGO which is more detailed than one might expect from such a small book, covering the observatory itself, the politics of collaboration and leadership, data analysis, and public relations in the shadow of the BICEP2 disaster.
