This book encloses a large variety of models in an introductory level and opens the possibility to the students to go deep in specific topics through its references. So, it is adequate for a regular course on complex systems. The mean-field part of book provides a concise, clear and complete presentation of dynamical systems. In my opinion, the agent-based chapters is well presented, but do not cover satisfactorily the criticality of epidemic spreading, a central point in complex system modeling.
