Fourteen and up for this second story of the career and heart interests of pretty, hard-working Penelope who is combining with her work as assistant to Dr. Drake, veterinary, the additional work on the committee of Dogs for Defense. Excellent informative background of the job -- and sound handling of the complex problems involved in Penelope's romance, -- to marry her soldier fiance now and risk the future; to obey her adult advisors or her own heart? Timely -- and of interest to teen age and up.
