The series Book 1-6 was promising, if annoying for having a cliffhanger ending that forced you to buy the next book, or specificially the Book 7 which contains all the endings.
Well after being built-up by books 1-6, wondering if the inconsistencies between those books would be tied together in ST Gateways Book 7, wondering if Book 7 "the grand conclusion of what lay beyond" would put forth a good explanation for the Iconian mystery, tie all the loose ends together and provide good conclusions for the cliffhanger endings of books 1-6...............it was most most most disappointing to see that this was not the case.
Book 7 creates more inconsistencies and the endings are [bad]. Oh some of the endings were ok, but the final ending...for the TNG book in the series...which was SUPPOSED to tie everything together, totally messed it up and failed, completely failed to deliver! I mean...first in books 1-6 they established that once activated a gateway cannot be destroyed no matter what they threw at it because it will simply absorb the energy. THEN in Book 7...suddenly Gateways CAN be destroyed by explosive force...no explanation given!!! Just a lazy author who didn't even read the previous book he wrote and ignored all stuff he established in the previous book! Once again, this is a MAJOR LETDOWN!
