"...Clancy established himself as an undisputed master at blending exceptional realism and authenticity, intricate plotting, and razor-sharp suspense..." (location 6141 on Kindle). Cameron continues with these attributes, offering perspective on what today's President experiences daily. I am glad that the cast of good people remains familiar, because new characters hail from many countries and backgrounds, varying from very evil to ethical. The various plots give equal opportunity to women, some who die and some who prevail. Jack Ryan the younger shows more maturity, guided by John Clark. The team spreads itself very thin, depleted by injuries as well. I spent more time than usual thinking about the connections and time lines in search of a logical path to the end of the story. Much that happens for President Jack Ryan can be illogical and nonlinear until details can be sorted by trusted staff and colleagues. Loose ends happen, waiting for another day or another novel. In addition, an angry opponent (Chadwick in this story) promises defiance and non-collaboration, challenging the best of ethical and social skills of the President. Yes - exceptional realism and authenticity portray a scary world out there.
