"The nature of dark matter is one of major outstanding questions in astrophysics and Ignacio Ferreras provides a clear and thorough overview of the fundamental aspects of the field. The text contains formal exercises to test comprehension of the material but also more thought-provoking 'How about..?' questions that deepen the reader's understanding. This book is an ideal introduction to an exciting and dynamic area of research and I recommend it highly for advanced undergraduates and beginning graduate students."
