This story was just so short. Honestly i read it out of curiousity of Grom's love life in Of Poseidon. 
 32 pages is not quite enough to squeeze in details, so all this book focuses on is the romance between Grom and Nalia. The plot is sweet (most, if not every, girl's dream) but would have bordered on the point of cheeziness had the story been any longer. There is very minimal character development, I suggest reading Of Poseidon first before starting on this one. 
 Legacy Lost hasn't explained anything in Of Poseidon, which is pretty fustrating. Should there be a follow-up to the latter, it sure should have one heck of an explainatipn to do.
