This is book one of the Etherclaw series and the main characters are Fenlee Harper (16) and her adopted brother Elliot (14), who live in the Lower Ashe Ward of New Cascadia. Her father adopted Elliot after finding him curled up with Fenlee, in the aftermath of the explosion where he lost his wife and Fenlee lost a leg. Elliot has no memories of his life before the explosion and is happy to have a friend and sister in Fenlee and for her father to adopt him, especially after losing his wife. Fenlee is an academy student and is always looking for scraps for her mechatronics projects and other stuff she likes to tinker with. The only things she has of her mothers are an opal necklace she always wears close to her heart and a small figurine. ON her latest trip to the abandoned undercity below New Cascadia, they run into trouble and Fenlee gets her prosthetic leg stuck when she falls through some loose debris, just as an autodrone could be heard coming to sweep the area. Elliot has to help her hobble away with the lightweight and expensive leg her father had recently bought her and a cat appears and seems to want them to follow it! Instead of a Sentry Class drone coming for them, she is shocked to see it is a Guardian Class autodrone and that has shot to kill authority, for anyone it finds in these areas. Just as she dives on top of Elliot to protect him, the drone explodes above them unexpectedly. She can’t figure out how or why.
The cat, Kavi, soon reappears along with a young barefooted boy called Nico and a very strong looking warrior type woman called Kyara. They live in this undercity along with other refugees without official citizenship for New Arcadia and make a living for themselves down there. Nico knows exactly what caused the explosion, Etherclaw, and points to the opal necklace Fenlee is wearing. He doesn’t speak much nor in proper sentences, but he always seems to know when danger is approaching! Etherclaw can be within a person, such as with Nico, or enclosed in an item such as Fenlee’s opal, and can be used in a multitude of different ways to redirect energy, usually closely linked to the person wielding it. There isn’t much information about it, but it seems to be something from the Aeons era, the beings who constructed the huge Void Pillars, just before the Great Collapse, saving mankind from certain death due to their destruction of the atmosphere. The pillars solved that issue, but there are some at Norfayne Labs that are experimenting with Etherclaw for their own purposes, trying to make superior beings and wipe out the rest. Nico and Kyara show them another way out of the undercity and they go back home, with Kyara telling Fenlee she will need to practise using the Etherclaw, if she wants any control over it and so she doesn’t use all of her own bioenergy to fuel its use.
When Fenlee decides to put her own creation into an airduct back by the Waterfront entrance to the undercity, she has Elliot are caught out by some guards from SecForce and are about to be detained until Kyara comes to their rescue. It is far too dangerous to go back for her little robot creation, but that doesn’t stop Elliot from sneaking off and being captured and taken to someone who tells him he is his father! Not that he treats him in any sort of humane manner, wanting his blood and torturing him to get the results he wants. Fenlee is desperate to get her only family back and has to rely on her friend Casper and the girl she is crushing on Alex, and Alex’s aunt Lily to come to her aid. But they aren’t the only ones going after Elliot’s supposed father, Dr Seth Arkamis, as others have a much longer history with him and want him to pay for what he did to them and others! A tragedy hits Fenlee, Elliot and Casper, as a deep space mining operation fails spectacularly, placing her under even more pressure to make a living and survive, as well as look after Elliot. Her family is down to just those chosen few and with Elliot taken by unknown forces, she will do anything to get him back. Thankfully Lily is a wise head and makes her stop and think before she acts, ensuring they don’t go off half-cocked and end up all dead or prisoners themselves. Strange things are happening in Elliot’s new surroundings, with a boy called Rook and a resident researcher aide Loxi, with them treating him so differently. He has no memories of any of these people, but soon wants to get back to Fenlee. The only problem is what he himself did in the past and the danger he could be to Fenlee and her friends in the present. He doesn’t believe he belongs in hr family anymore, but she will discover how to use the opal and all its costs to her and others, just to get the last of her family back where he belongs. An additional twist at the end which leads nicely onto another book to follow in the series. I look forward to reading it when it comes out and finding out what happens to all of the characters. I received an ARC copy of this book from BookSprout and I have freely given my own opinion of the book above.
