There are kids’ writers who have some pretty decent books out, still. Surprising? IKR? *heh*
I recently read the first two books in a juvie (“YA”-ish) semi-hard sci-fi and feel I can recommend them for my Wonder Woman’s libraries (though they’re only available in ebook and paperback *sigh* Both formats have school library problems). They’re about the level of the Tom Swift, Jr. sci-fi in terms of actual hard science, IOW, more hand-waving than _actual_ science, and the kind of fudging of science foundations that had me sometimes rolling my eyes in 4th grade, but still better written and with a much more “civilized” world view than many YA books nowadays. (Yes, I still submitted word usage errors for correction, but not as many as I have come to expect in even tradpub books nowadays.)
The series begins with Awakening by Randal Sloan.
Six books in the series, but I think 2 will do it for me. As with most juvies, the plots and characters are just too predictable – a net positive for YA/juvie books, IMO, but less so for most adult readers.
Another series I am even more sold on is the City Spies series by James Ponti. Yes, the characters and plots are pretty standard (with some interesting variations), but the books are just so very well-written (and pretty darned well edited!) that the first chapter of book 1 (read at a school librarians conference) sold me on the series. And yes, my Wonder Woman reports that her students are rightly as appreciative of the books as I am. 🙂
