Every chapter has interesting graphics. As a `star person , I particularly like the clear depiction of Roche geometry and of maximum sizes of stars at various phases in the discussion of common-envelope binaries. The treatment of the history of each topic is, at best, spotty. And every author is eager for the next, larger telescope, detector, satellite, or computer. Most are young, at least by my standards, and so their hopes may yet be fulfilled. (Virginia Trimble, The Observatory, Vol. 141 (1285), December, 2021)
