Yes and if truth be told, I sometimes kind of tend to wish that especially with regard to Marguerite Henry's Sea Star: Orphan of Chincoteaque (the second of Henry's Misty of Chincoteague novels), I had not decided a few years ago to check online resources about the real-life happenings that precipitated Sea Star: Orphan of Chincoteaque. For the optimistic and intensely hopeful ending of Sea Star: Orphan of Chincoteaque is in fact more than a bit of a total fantasy and fairy tales, since the sad truth of the matter regarding the actual Sea Star is that he did not survive, that he in fact died, something that does make me rather majorly sad whenever I now do reread Sea Star: Orphan of Chincoteaque (although realistically speaking and as someone familiar with horses, horse breeding and their care, I actually do well know from first hand family experience just how difficult and at times even impossible successfully raising and caring for an orphaned foal can be).
But all the above having been said, and if I in fact just choose to read Sea Star: Orphan of Chincoteaque as a story in and of itself and with nothing attached (with no consideration of what actually happened regarding Sea Star in real life), yes, as a horse themed novel for children, I absolutely and in every way consider Sea Star: Orphan of Chincoteaque not only a more than worthy sequel to Misty of Chincoteague, but that there are actually a number of parts and points regarding Marguerite Henry's presented plot, of the basic storyline of Sea Star: Orphan of Chincoteaque that I in fact appreciate even somewhat more than Misty of Chincoteague (and especially as an adult reader).
For example, while in Sea Star: Orphan of Chincoteaque, Maureen Beebe is still being shown by Henry as having rather more house-based (read inside) chores to do than her brother Paul (and considering both the time and place of Sea Star: Orphan of Chincoteaque, this is not all that unusual, and is in fact personally appreciated realism), I much like, I do very much enjoy that for the most part, Maureen is actually never all that much overburdened with housework, is thus not expected to constantly be helping Grandma Beebe in the kitchen (and that in Sea Star: Orphan of Chincoteaque, Maureen is really only at the very beginning of the novel responsible for the entire housework getting done, and this is only because Grandma Beebe is away for the day on important errands, and of course, the house needs to be cleaned, the beds need to be made and supper prepared). And therefore, while in and throughout Sea Star: Orphan of Chincoteaque Maureen does indeed have somewhat more inside chores and errands to perform than her brother, than Paul, there is at least in my opinion, never in any way a sense of Maureen being narratively criticised by the author, by Marguerite Henry for preferring to muck out horse stalls, for preferring to care for Grandpa Beebe's ponies than helping her grandmother clean house or cook meals (and also once again, and like in Misty of Chincoteague, the vast majority of misogyny, the vast majority of comments against or critical of "girls" present in Sea Star: Orphan of Cincoteague come not from Grandpa and Grandma Beebe, come not from the Fire Chief, the movie executives etc., but from Paul Beebe, and with him, I again and still consider these jabs and verbal put-downs more a case of sibling squabbles, of sibling rivalry, of an older brother trying to feel and act superior towards a younger sister, and with thankfully and appreciatively, Henry also depicting, describing Maureen as increasingly verbally fighting back against this).
Now with regard to Misty in Sea Star: Orphan of Chincoteague being sold to those two movie producers (executives), I feel a bit like Paul and Maureen are described by Marguerite Henry as feeling, that instead of despising Mr. Van Meter and Mr. Jacobs, I rather do like them both on a personal level. But this general affection and regard notwithstanding, I still strongly also believe that the two men should absolutely have waited for Grandpa Beebe to show up before even considering discussing Misty and their plans to purchase her for a movie project, for as Grandpa Beebe so clearly points out, adults should not be "horse trading" with children (and although I do very much feel intensely proud of the fact that Paul and Maureen decide to sell Misty to Mr. Van Meter and Mr. Jacobs in order for their uncle to be able to attend college, I find it frustratingly saddening that this has even been necessary, that the children have to sell Misty in order to obtain the necessary tuition funds for Clarence Lee, that there are seemingly no scholarships, student loans or bursaries available for potential students with limited financial means).
And finally, while I certainly do understand and appreciate that both Paul and Maureen originally very much chafe at Grandpa Beebe's insistence that little Sea Star NOT be bottle fed, not be hand reared so to speak, I am very much glad that they heed their grandfather's dictum and also, concurrently, that the author also clearly and realistically textually shows and demonstrates in Sea Star: Orphan of Chincoteaque to her readers exactly why, that Henry does not simply have Grandpa Beebe declare a categorical NO with regard to bottle feeding Sea Star without an adequate explanation (because it really and truly is majorly problematic and difficult to successfully raise, to successfully hand feed a foal with a bottle, and the scenario described by the grandfather of a hand reared, bottle fed foal becoming increasingly spoiled, unmanageable and even potentially dangerous as it ages, as it gets larger and more powerful is a realistic, is a bona fide concern, which is why, for orphaned foals, or for foals where the mare does not produce sufficient milk, it is ALWAYS generally better if not necessary to find a suitable replacement, a nurse mare).
Four stars, brightly, shiningly glowing for Marguerite Henry's Sea Star: Orphan of Chincoteaque, and even though the actual and true reality of the little orphaned foal which story the author used in her novel did not have an equally positive outcome, I do love love love especially the sweet and oh so gently evocative ending of Sea Star: Orphan of Chincoteaque (with Paul and Maureen Beebe receiving both Sea Star and his "new" mother from Wilbur Wimbrow, two very special Chincoteague ponies, to take their minds off constantly missing Misty, until her movie shooting days end and she is able to return to the family).
