So glad I took the time to read this. Now I'll have to check out Protostar. Broken Prince is extremely well-written and, the best word that comes to mind is 'vivid'. Like the cover (love, love, love the cover), the writing/world building is sharp and richly detailed and carries the reader through William's quest for indep. and his desire to follow his own path and also the pull of obligation, which leads him to prep for his mission in Protostar. Very well done. And again, that cover-WOW.
