Rose Point (Her Instruments Book 2). Her Instruments, #2

Reese is only just getting used to running the Earthrise in the black-and with an Eldritch in her crew-when a trip to a colony world gives rise to a whole new problem: Hirianthial is showing powers that even the Eldritch rarely have, and that only in legend. He badly needs training, support and advice, and the only place he can find them is... at home. To see the world of the Eldritch is a once in a lifetime opportunity, a thing of fantasies and rumor.
And to finally meet the Eldritch Queen, the author of so many of Reese's windfalls! You'd have to twist her arm to get her to admit it, but Reese can't wait to go. But a court out of fantasy and a breathtaking land aren't enough compensation when they come packaged with a rabidly xenophobic species whose world is falling apart. The last thing they want any part of is some mortal interloper. Is Reese ready for the Eldritch world? Better to ask: are they ready for her?
